Concept:
Quantitative research is focused on the systematic empirical investigation of observable phenomena via statistical, mathematical, or computational techniques.
Step 1:
Quantitative data analysis requires tools that handle numerical information. "Statistical Analysis" (C), "Measure of Central Tendency" (D), and "Tabulation of data" (E) are essential techniques for summarizing and analyzing numerical datasets.
Step 2:
"Cultural artifacts" (A) and "Archival manuscripts" (B) are typically sources for qualitative research, where the focus is on content, historical context, or meaning, rather than numerical frequency or statistical distribution.
Step 3:
Because C, D, and E are the primary methods for processing numerical data, they form the correct set.
Step 4:
Options C, D, and E define the core toolkit for quantitative data analysis, making option (4) the correct choice.
