Do You Think Gender Plays a Pivotal Role in Job Classification?

QUESTION :1

Do you think gender plays a pivotal role in job classification?

SOLUTION  - Chi Square Test calculation using excel-

Null Hypothesis H0 : Gender does not play a pivotal role in job classification.

Alternate Hypothesis H1: Gender plays a pivotal role in job classification

Assuming the null hypothesis is true, we perform the chi square test.

[pic 1]From the Chi square test table, the value of chi square is 79.277 and asymptotic significance is .000 ie p value = 0.000 which is a very small value ( <0.05). Therefore, we can reject our null hypothesis.

This implies that, the alternative hypothesis is true ie. there is strong co-relation between gender and employment category.

QUESTION :2

Do you think gender plays a pivotal role in salary discrimination?

SOLUTION

H0 : Gender does not play a pivotal role in salary discrimination.

H1: Gender plays a pivotal role in salary discrimination

Since there is one categorical variable (gender) and one continuous variable (current salary), we can compare the means for the two genders.

CALCULATION USING EXCEL –

Assuming the null hypothesis is true, we get the mean as 17016.0865(for male and female combined).

Since the group average current salary for males and females is different and is not equal to the combined mean, we can say that the gender plays a role in salary discrimination.

Checking results from Conducting Independent t test using SPSS also

[pic 2]

We see that the group means of male and female are statistically different and this also relates with the p value 0.000 (sig (two tailed value)) from independent samples test table. Since p value is less than 0.05 we reject the null hypothesis and accept the alternate hypothesis and conclude that gender plays a pivotal role in salary discrimination.

QUESTION 3:

Predict Salary of an employer with job category manager, beginning salary 30,000, job time 97 and previous experience 100.

SOLUTION

Performing regression using SPSS, keeping salary as dependent variable and job category, beginning salary, job time and previous experience as independent variables, we get the following results.
