Explanation
Sample Size (D) refers specifically to the count of individual units (people, objects, observations) included in a sample - it's literally "how many" are in your sample.
- Population (A) is the entire group being studied, not a count of units in a subset.
- Mode (B) is the most frequently occurring value in a dataset - a measure of central tendency, not a count.
- Mean (C) is the arithmetic average of values - again a calculated statistic, not a count of units.
Memory tip: Think of "size" literally - sample size answers the question "how big is the sample?" just like clothing size answers "how big is the shirt?" It's always a whole number (you can't have 2.5 people).
