Factor analysis is used for: (A) data entry (B) data distribution (C) data reduction (D) data separation Correct Ans: (C) Explanation:Researchers use factor analysis to reduce large datasets into smaller, more meaningful groups. Instead of analyzing each variable separately, they identify patterns and combine related variables into broader categories called factors. This method works by […]

One of the important ways to ascertain the range of spread of variables in a sample is through the calculations of: Correct Ans: (D) Explanation:Researchers often deal with data that varies within a sample. To understand this variation, they calculate the standard deviation. This method shows how far each data point strays from the average

Non – parametric tests are the statistical tests that measure the variable at: (A) probability level (B) ratio level (C) interval level (D) nominal level Correct Ans: (D) Explanation:Non-parametric tests measure variables at the nominal level. Nominal level data represents categories that have no inherent order. These tests do not rely on assumptions about the
