The definitions and equations all apply regardless of the amount of data. The only important metric in statistics regarding sample size is the reliability and accuracy of the results.

Explanation:

The definitions and equations all apply regardless of the amount of data. The only important metric in statistics regarding sample size is the reliability and accuracy of the results. Smaller samples have inherently higher error margins for statistical measurements than larger ones.
The mean is the simple arithmetic average of the five numbers. The median is the value that is at the midpoint of the total range of the numbers. The mode is the most frequently occurring number in the data set.
