Cohen’s d was calculated to determine the practical significance of the above difference, as shown in Table 7. It is apparent that a large practical significance exists between Africans and Coloureds regarding the use of LinkedIn for recruitment purposes (d > .80).

T-Tests
t-Tests were calculated to determine whether any gender differences occurred for Recruitment Facebook and Recruitment LinkedIn. Based on Table 8, it is apparent that for Recruitment Facebook and Recruitment LinkedIn, the p-values are greater than the significance level of 0.05. Thus, there is no statistically significant relationship between these factors and the gender variable. In conducting a t-test for dependent means (Table 9), the sample had a t-score of 9.321, which is more than the extreme cut-off t of 1.99.

Tables 10 and 11 illustrate the results of t-tests conducted to conclude whether any differences occur for Recruitment Facebook and Recruitment LinkedIn when comparing respondents working as HR professionals with those with other employment statuses. From Table 10 it is evident that there is a statistically significant difference between those respondents employed in HR and those respondents employed in recruitment agencies, in terms of their perception of using Facebook for recruitment purposes, as the p-value is less than the significance value of 0.05. This difference holds a large practical significance (d>.80). The direction of the means imply that those respondents working in recruitment agencies are more inclined to use Facebook for recruitment purposes than those working within HR.
