Correct Answer:
Option D —
Tabulation facilitates comparison between rows and not columns
Statement A (True): Tabulation is one of the most effective ways to summarize large volumes of "raw" or complicated data into a logical, structured format.Statement B (True): You cannot create a bar chart, pie chart, or histogram accurately without first organizing the data into a table. The table provides the precise numerical coordinates needed for the diagram.
Statement C (True): Most statistical operations (calculating the mean, variance, or correlation) require data to be classified and tabulated so that the relationships between variables can be analyzed systematically.
Statement D (FALSE): This is the incorrect statement. The primary purpose of a table is to facilitate comparison both horizontally (across rows) and vertically (down columns). For example, a table of "Sales by Region" allows you to compare different regions (rows) and different time quarters (columns) simultaneously.
