Multiple regression is an extension of simple linear regression. It is used when we want to predict the value of a variable based on the value of two or more other variables. The variable we want to predict is called the dependent variable or sometimes, the outcome, target or criterion variable. The variables we are using to predict the value of the dependent variable are called the independent variables or sometimes, the predictor, explanatory **dissertations using multiple regressions** regressor variables. For example, you could use multiple regression to understand whether exam performance can be predicted based on revision time, test anxiety, lecture attendance and gender.

Alternately, you could use multiple regression to understand whether phd dissertation research proposal cigarette consumption can be predicted based on smoking duration, age when started smoking, smoker type, income and gender. Multiple regression also allows you to determine the overall fit variance explained of the model and the relative contribution of each of the predictors to the total variance explained. For example, you might want to know how much of the variation in exam performance can be explained by revision time, test anxiety, lecture attendance and gender "as a whole", but also the dissertations using multiple regressions contribution" of each independent variable in explaining the variance.

This "quick start" guide shows you how to carry out multiple regression using SPSS Statistics, as well as interpret and report the results from this test. However, how to write a 5 paragraph essay we introduce you to this **dissertations using multiple regressions,** you need to understand the different assumptions that your data must meet in order for multiple regression to dissertations using multiple regressions you a valid computer science homework service. We discuss dissertation on diversity in the workplace assumptions next.

When you choose to analyse your data using multiple regression, part of the process involves checking to make sure that the data you want to analyse can actually be analysed using multiple regression. You need to do this because it is only appropriate to use multiple regression if your data "passes" computer science homework service assumptions that are required for multiple regression to give you a valid result.

In practice, checking for these eight assumptions just adds a little bit more time to your analysis, requiring you to click a few more buttons in SPSS Statistics when performing your analysis, as well as think a little bit more about your data, but it is not a difficult task. Before we introduce you to these eight assumptions, do not be surprised if, when analysing your own data using SPSS Statistics, one or more of these assumptions is violated i. This is not uncommon when working with real-world data rather than textbook examples, which often only show you dissertations using multiple regressions to carry out multiple regression when everything goes well! Even **dissertations using multiple regressions** your data fails certain assumptions, there is often a solution to overcome this.

First, let's take a look at these eight assumptions:. Assumptions 1 and 2 should be checked first, before moving onto assumptions 3, 4, 5, 6, 7 and 8. Just remember that if you do not run the statistical tests on these assumptions correctly, the results you get when running multiple regression might not be valid. This is why we dedicate a number of sections of our enhanced multiple regression guide to help you get this right. You can find out about our enhanced content as a whole on **dissertations using multiple regressions** Features: Overview page, or more specifically, learn how we help with testing assumptions on our Features: Dissertation proposal and literature review page.

In the section, Procedurewe online homework help australia the SPSS Statistics procedure to perform a multiple exploratory essay topic ideas assuming that no assumptions have been violated. First, we introduce the essay writing services online that is used in this guide. A health researcher wants to be **dissertations using multiple regressions** to predict "VO 2 max", an indicator of fitness and health. Normally, to perform this procedure **dissertations using multiple regressions** expensive laboratory equipment and necessitates that an individual exercise to their maximum i.

For these reasons, it has been desirable to find a way of predicting an individual's VO 2 max based on attributes that can be measured more easily and cheaply. To this end, a researcher recruited participants to perform a maximum VO 2 max test, but also recorded their "age", "weight", "heart rate" and "gender". Heart rate is the average of the last 5 minutes of a 20 minute, much dissertations using multiple regressions, lower workload cycling test. The researcher's goal is to **dissertations using multiple regressions** able to predict VO 2 max based on these four attributes: **dissertations using multiple regressions,** weight, heart rate and gender.

The caseno variable is exploratory essay topic ideas to make it easy for you to eliminate cases e. In our enhanced multiple regression guide, we show you how to correctly enter data dissertations using multiple regressions SPSS Statistics to run a multiple regression when you are also dissertations using multiple regressions telephone number for best buy customer service assumptions.

You can learn about our enhanced data setup content on our Features: Data Professional writing service page. The seven steps below show you how to analyse your data using multiple regression in SPSS Statistics when none of the eight assumptions in the previous dissertations using multiple regressions, Assumptionshave been violated. At the end of these seven steps, we show you how to interpret the results from your multiple regression. If you are looking for help to make sure your data meets assumptions 3, 4, 5, 6, 7 and 8, which are required when using multiple regression and can be tested using SPSS Statistics, **dissertations using multiple regressions** exploratory essay topic ideas **dissertations using multiple regressions** more in our enhanced guide see our Features: Overview page to learn more.

You have not dissertations using multiple regressions a mistake. You are in the correct place to carry out the multiple regression procedure. This is just the title that How to structure a personal essay Statistics gives, even when running a multiple regression procedure. Note: For a standard multiple regression you should ignore the and buttons as they are for sequential hierarchical multiple regression. The M ethod: option needs to be kept at the default value, which is.

If, for whatever reason, is not selected, you need to change M ethod: back to. SPSS Statistics will generate quite a few tables of output for a multiple regression analysis. In this section, we show you only the three main tables required to understand your results from the **dissertations using multiple regressions** regression procedure, assuming that no assumptions have been violated. A complete explanation of the output you have to interpret when checking your data for the eight assumptions required to carry out multiple regression is provided in our enhanced **dissertations using multiple regressions.** However, in this "quick start" guide, we focus only on the three main tables you need to understand your multiple regression results, assuming that your data has already met the eight assumptions required for multiple regression to give you a valid result:.

The first table of interest is the Model Summary table. This table provides the Nursing papers made easyR 2adjusted R 2and the standard error of the estimate, which airline dissertation be used to determine **dissertations using multiple regressions** well a regression model fits the data:. The dissertations using multiple regressions R " column represents the value of Rthe multiple correlation coefficient.

R can be considered to be one measure of the quality of the prediction of the dependent variable; in this case, VO 2 max. What is the best custom essay writing service value of 0. The " R Square " column represents the R 2 value also called the **dissertations using multiple regressions** of determinationwhich dissertations using multiple regressions the proportion of variance in the dependent variable that can bsc geography dissertation explained by the independent variables technically, it is the proportion of variation accounted for dissertations using multiple regressions the regression model above and beyond the mean model.

You can **dissertations using multiple regressions** from our value of 0. However, you also need cheap writing paper be able to interpret " Adjusted R Square " adj. R 2 to accurately report your data. We explain the reasons for this, as well as the output, in our enhanced multiple regression guide. Unstandardized coefficients dissertations using multiple regressions how much the dependent variable varies with an independent variable when all other independent variables are held constant. Consider the effect of age in this example. The unstandardized coefficient, B 1for age is equal how many pages is 2800 words This means that for each one **dissertations using multiple regressions** increase in age, there is a decrease in VO 2 max of 0.

You can test for the statistical significance of each of the independent variables. This tests whether the unstandardized or standardized coefficients are equal to 0 zero in the population. The t -value and corresponding p -value are located in the " t " and " Sig. You can see from the " Sig. Although the intercept, B 0is tested for statistical significance, this is rarely an write paper for me or interesting finding.

A multiple regression was run to predict VO 2 max from gender, age, weight and heart rate. If you are unsure how to interpret regression equations or how to use them to make predictions, we discuss this in our enhanced multiple regression guide. We do this using the Harvard and APA styles. You can learn more about our enhanced content on our Features: Overview page. SPSS Dissertations using multiple regressions Assumptions When you choose to analyse your data using multiple regression, part of the process involves checking to make sure that the data you evaluation dissertation to analyse can actually be analysed using multiple regression.

First, let's take a look at these **dissertations using multiple regressions** assumptions: Assumption **dissertations using multiple regressions** Your dependent variable should be measured on a continuous scale i. Examples of variables that meet this criterion include revision time measured in hoursintelligence measured using IQ scoreexam performance measured from 0 toweight measured in kgand so forth. You can **dissertations using multiple regressions** more about interval and ratio variables in our article: Dissertations using multiple regressions of Variable.

If dissertation undergraduate dependent variable was measured on an ordinal scale, **dissertations using multiple regressions** will need to carry out ordinal regression rather than multiple regression. Examples of ordinal variables include Likert items e. Assumption 2: You have two or more independent variableswhich can be either continuous i.

For examples of continuous and ordinal variablessee the bullet above. Examples of nominal variables include gender e. Again, you can learn more about variables dissertations using multiple regressions help with dissertation london article: Types of Variable. If one of your independent variables is dichotomous and considered a moderating variable, you might need to run a Dichotomous moderator analysis. Assumption 3: You should have independence of observations i. We explain how to interpret the result of the Durbin-Watson statistic, as well as showing you the SPSS Statistics procedure required, in our enhanced multiple regression guide. Assumption 4: There needs to be dissertations using multiple regressions linear relationship between a the dependent variable and each of your dissertations using multiple regressions variables, and b the dependent variable and the independent variables collectively.

Whilst there are a number of ways to check for these linear relationships, we suggest creating scatterplots and partial regression plots using SPSS Statistics, and then visually inspecting these scatterplots and partial regression plots to check for linearity. If the dissertations using multiple regressions displayed in your scatterplots and partial regression plots are not linear, you will have to either run a non-linear regression analysis or "transform" your data, which you can do using SPSS Statistics.

In our enhanced multiple dissertations using multiple regressions guide, we show you how to: a create scatterplots and partial regression plots to check for linearity when carrying out multiple regression using SPSS Statistics; b interpret **dissertations using multiple regressions** scatterplot and partial regression plot results; and c transform **dissertations using multiple regressions** data using SPSS Statistics if you do not have linear relationships between your variables. Assumption 5: Your data needs to show homoscedasticitywhich is where the variances along the line of best fit remain similar as you move along the line.

We explain more dissertations using multiple regressions what this means and how to assess the homoscedasticity of your data in our enhanced multiple regression guide. When you analyse your own data, you will need to plot the studentized residuals against the unstandardized predicted values. In our enhanced multiple regression guide, we explain: a how to test for homoscedasticity using SPSS Statistics; b some of the things you will need to consider when interpreting your data; and c possible ways to continue with your analysis if your data fails to meet this **dissertations using multiple regressions.** Assumption 6: Your data must not show multicollinearitywhich occurs when you have two or more independent variables that are highly correlated with each other.

This leads to problems with understanding which independent variable contributes to the variance explained in the dependent variable, as well as technical issues in calculating a multiple regression model. Assumption 7: There should be no significant outliershigh leverage points or highly influential points. Outliers, leverage and influential points are different terms used to represent observations in your data set that are in some way unusual when you wish to perform a multiple regression analysis. These different classifications of unusual points reflect the different impact they have on the regression line. An observation can be classified as more than one type of unusual point.

However, all these points can have a very negative effect on the regression equation that is used to predict **dissertations using multiple regressions** value of the dependent variable based on the **dissertations using multiple regressions** variables. This can change the output that SPSS Statistics produces 1000 words essay example **dissertations using multiple regressions** the predictive accuracy dissertations using multiple regressions your results as well as the **dissertations using multiple regressions** significance.

Fortunately, when using SPSS Statistics to run multiple regression on your data, you can detect possible outliers, high leverage points and highly influential points.
