Which of the following results would represent statistical significance, if the level of significance were set at .05 for each? (Select all that apply.)
a. t = 8.43, p <.01
b. X2 = 10.83, p <0.1
c. F = 2.37, p <0.07
d. r = 0.2, p = .23
e. rs = .74, p = .049
ANS: A, E
The obtained result from the calculation of the statistic is compared with the appropriate table, at the level of significance set by the researcher at the outset of the study. If that is p <.05, it is essential that the correct value be retrieved from the table, for comparison. Researchers often set the level of significance at .05. By that criterion, the two statistically significant values above are p <.01 and p = .049.
