Answer:
The correct response is Option B: Detailed in-depth information is needed.
Explanation:
Of the options provided the best reason for choosing interviews as your research methodology is that the study is aimed at gleaning detailed information on a subject and there needs to be an effort to dive deep into the data. The disadvantage of this method is that it tends to be time-consuming and the analysis needs to be done more manually than the results of a survey. Surveys are more amenable to using software and running statistical analyses although some software exists for helping to analyze qualitative data as well. Interviews can also be useful for uncomfortable subjects although in some populations they may prefer the anonymity of a survey if the research is on a sensitive subject.
Answer:
- Explanatory
Explanation:
<u>Explanatory variable</u> is elucidated as the variable that could affect the response variable. This variable is quite identical with the independent variable as it can be controlled or changed that may affect the response variable(which is similar to dependent variable). However, the observational studies observe the natural responses without any manipulation and therefore, these variables cannot be changed always. In the given example, the 'number of hours spent on studying for the test' would be the explanatory variable as it directly influences the response variable i.e. 'grades.'
