Answer 1

Here' the answer to the question. Please don't hesitate to give a "thumbs up" in case you're satisfied with the answer

Descriptive statistics uses the data to provide descriptions of the population, either through numerical calculations or graphs or tables.

D.

In the first table, the sample have been divided into Age groups, Race, gender, mairital status etc, which are descreptives of a population. Hence, this table is Descriptive statistics

Take example of Woman,%: This means that out of the sample of n=2802, how many were women:75.9%, the
rest 24.1% were men

E.

Inferential statistics makes inferences and predictions about a population based on a sample of data taken from the population in question. Thus, the pp-value(net effect size) is inferential statistics. It tells whether net effect size
is statistically significant or not .

For example, Within Memory testing , Memory measure' net size effect is .257, and this is statistically significant
since p-value is less than .05 ( it is < .001 as per the table actually)
