Regression Analysis and ANOVA

This assignment consists of three separate analyses: one on the relationship between two variables (Totalfamilyfunctioning and maritalstatus), another on the effect of a variable (sexualabuse) on Totalfamilyfunctioning, and a third analysis on the effect of another variable (levelofeducation) on Totalfamilyfunctioning. The first analysis uses ANOVA to determine if there is a significant difference between the mean values of Totalfamilyfunctioning for different levels of maritalstatus. The second analysis uses regression analysis to see if sexualabuse has a significant effect on Totalfamilyfunctioning, and the third analysis also uses regression analysis to examine if levelofeducation has a significant impact on Totalfamilyfunctioning.
