Interpreting a Higher Average indicates what?

Interpreting a Higher Average indicates what?

• A. Indicates a higher level of that measured variable within a group.
• B. Indicates a larger sample size.
• C. Indicates more measurement error.
• D. Indicates more missing data.

Answer: (A)

A higher average shows a higher central value for the measured variable within the group. The average, or mean, summarizes the typical level of the variable across individuals, so when one group has a higher mean than another, it indicates that, on average, members of that group exhibit larger values on that variable. This tells you about the typical level, not about how many observations you have, so a larger sample size doesn’t by itself cause the mean to rise. It also doesn’t inherently reveal more measurement error or more missing data, which affect reliability or data completeness rather than the central value.
