Correlation Analysis
LEARNING OBJECTIVES
Upon completing this chapter, you should be able to do the
following:
State the similarities and differencesbetween multiple regression, factor
analysis, discriminant analysis, and canonical correlation.
Summarize the conditions that must be met for application...
This section covers procedures for testing the differencesbetween two means using the SPSS Compare Means analyses. Specifically, we demonstrate procedures for running Dependent-Sample (or One-Sample) t-tests, Independent-Sample t-tests, Difference-Sample (or Matched- or Paired-Sample) t-tests. Unfortunately...
Both one-sample hypothesis testing and regression analysis uses the obtained sample to analyse the data and make predictions.
The first difference is that the aim of regression analysis is to determine the values of parameters for a function that cause the function to best fit a set of data obsevations...
and design experiments to test hypotheses.
3. Analyze data using basic statistical techniques.
4. Identify and distinguish betweendependent, independent, and control variables.
5. Present experimental data using appropriate tables, figures, and graphs.

Types of Variables
Binary variable
Obsevations (i.e., dependentvariables) that occur in one of two possible states, often labelled zero and one. E.g., “improved/not improved” and “completed task/failed to complete task.” Usually an independent or predictor variable that contains values indicating...
toward the mean, and selection differences.
History is a treat to internal validity for the one group design due to some unanticipated event that can occur during the experiment and may affect the dependentvariable. Maturation is where change occurs in the dependentvariable due to normal developmental...
occupational testing carried out by Sadri et al (1996). Their results ‘demonstrate the invariance of the postulated stress model in which individual differences such as personality and coping were shown to precede and determine the perception of job stressors, which in turn has an impact on the wellbeing...
associated with different values of one variable and to express these counts in percentage terms. ; frequency distribution for a variable produces a table of frequency counts, percentages, and cumulative percentages for all the for all the values associated with that variable. ; Conducting Frequency Analysis...
estimating the relationship between Human development index (HDI) and its components. Linear Regression is a statistical technique that correlates the change in a variable to other variable/s, the representation of the relationship is called the linear regression model.
Variables are measurements of occurrences...
scientific method.
Scientific Method is a solving a problem efficiently and effectively.

4. Observations
5. Data and Results
6. Conclusion
3. Form a hypothesis from one or more observations.
A hypothesis...
statistical tests best suited for this type of data is correlation. Correlation is a bivariate measure of association (strength) of the relationship between two variables. It varies from 0, which indicates not relationship or a random relationship to one, which is a perfect linear relationship or to –1, which...
rejecting or accepting the null and alternative hypotheses. Going along with the first step, the null hypothesis is that There is no significant differencebetween Peter Reardon's methodology for forecasting inventory and the observed sales for Burns Auto. The null hypothesis statement is the statement...
graphs (histograms, boxplots, etc) or numerical summaries
3. Define each of the following terms:
a) Variable
The topics/issues under investigation in statistical analysis. The variable is a characteristic or property of the members of the population which may vary e.g. height, weight, perception...

A definition of experiments
An experiment involves the creation of a contrived situation in order that the researcher can manipulate one or more variables whilst controlling all of the others and measuring the resultant effects. For instance, when United Fruits were considering replacing their Gros Michel...
macroeconomic variables on net assets of multinational companies operating in Nigeria with the aim of identifying how level of interest rate affect the net assets of these companies. Increased integration and growing macroeconomics fluctuations requires more attention to be paid to link between the “noise”...
