Question

Dr. Salazar recently completed an experiment in which she compared reasoning ability in a sample of females and a sample of males. The means of the female and male samples equaled 21 and 19 respectively, on a 25-point scale. A statistical test revealed that her results were not statistically significant. What can Dr. Salazar conclude?

Answer 1

The difference in the means of the two samples is probably due to chance variation.

Step-by-step explanation:

People's ability to reason is influenced by several factors, among which we can consider genetics, the environment in which the person was raised, the level of education, the type of education, among other things. Each person's gender is not a factor that necessarily influences reasoning ability, since reasoning is an individual thing and not linked to gender. For this reason, Dr. Salazar's statistical tests revealed that his research results were not statistically significant. This means that reasoning ability is not determined by people's gender, so the result for Dr. Salazar's research is that the difference in the averages of the two samples is probably due to chance variation.
