Question

current attempt in progress
which of these is a measure of variation?
o range
o median
o mean
o mode

Explanation:

• Range: It is calculated as \( \text{Range}=\text{Maximum value}-\text{Minimum value}\) in a data - set. It gives an idea about how spread out the data is, so it is a measure of variation.
• Median: It is the middle - value of a sorted data - set. It represents the central tendency of the data, not the variation.
• Mean: It is the average of a data - set (\(\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}\)). It is a measure of central tendency.
• Mode: It is the most frequently occurring value in a data - set. It is also a measure of central tendency.

Answer:

range
