The group statistics and the independent samples test results
The differences between the group of women with a positive score on the ASLR test and the
group of women with a negative score on the ASLR test is significant according to the “t-test”
at the DPQ total score, the DPQ physical score and the DPQ emotional capacities.
The Levene's test for equality or variances shows that all tests have a normal distribution of
the population.
A normal distribution of the population goes through a hystogram. The t-test gives the
probability (significance) to the observed differences.
Women with a positive ASLR test had a higher total score on the DPQ. The probability is
here higher then 95%. The score on the physical activities of the DPQ was also significantly
higher for women with a positive ASLR test. Also here the probability is higher than 95%.
The difference in the score for the DPQ emotional capacities for women with a positive
ASLR test was also clearly significant (p
