Homework Answers
1. The statistical technique applied could be "ANOVA".Anova is basically used to find the difference among various group means by analyzing their variance. The different groups can be taken as the three classified age groups.
2.The statistical technique applied could be "logistic binary regression ". Here we need to find how gpa scores affect finding a job.The dependent variable "find a job" is dichotomous variable. The logistic regression is form of simple linear regression when the dependent variable is dichotomous in nature.
3.The statistical method applied could be "regression " .with the help of dummy variables.
Thanks.
