A-B-A-B design could provide the most valid non intervention measure with demonstration of experimental control.
In statistics, the experimental design, also known as the design of experiment (DOE), is described as the layout of an information-gathering experiment in which a variation may or may not be present. Typically, controlled experiments use this phrase. In order to make the results more reliable, these tests minimize the impacts of the variable. In this design, a group of people, plants, animals, etc. may participate in an experimental unit's procedure.
Pre-experimental research designs are the most straightforward kind of experimental research designs in statistics. Following the identification of some factors as causes and effects, a group or groups are kept under observation in this method. Typically, this approach is used to determine whether the targeted group need additional research. This is the reason why this procedure is regarded as being economical.

Answer:
Correlation 1 between income & number of years in school is moderate positive. Correlation 2 between number of close friends & depression level is moderate negative correlation.
Explanation:
Correlation is a statistical measure showing relationship between variables' direction of movement. It lies between 0 &1.
Positive Correlation means variables move in same direction, one variable increase implies other variable increase & vice versa.
Correlation 1 between income & number of years in school is positive correlation. So, higher income implies more years in school & vice versa.
Negative Correlation means variables move in opposite direction, one variable decrease implies other variable increase & vice versa.
Correlation 2 between number of close friends & depression level is negative correlation. So, more close friends imply lower depression level & vice versa.
Correlation 1 is moderate positive correlation (between 0.25 & 0.75). Correlation 2 is also moderate negative correlation (between -0.25 & -0.75)

He even duplicated his proposition regarding the distinct rates of obedience among men and women. Therefore, <u>option B</u> becomes the correct answer to this question.
