QUESTION FOUR: (a) Explain the data requirements for the following; (i) Correlation analysis- (ii) Analysis of variance-. (iii) Bivariate regression- (iv) Binary logistic regression-

a)

Here, we have to explain the data requirements for the given for types of analysis or methods.

Correlation means how the change of one variable affects the change of other variable. In statistics, correlation analysis used to find any association between to variables.

Analysis of variane(ANOVA) means separation of variance ascribable to one group of causes from the variance ascribable to other group. Mainly, ANOVA is a powerful statistical tool for tests of significance.

Bivariate regression is a type of statistical analysis that examines the relationship between two variables. Actually it is used to find the mathematical equation that describes how two variables are related.

Binary logistic regression is a statistical method that models the probability of an event occurring based on one or more predictor variables.
