The correct answer is B. Correlation.
A measure of central tendency is a way of describing the central or typical value of a set of data. The three most common measures of central tendency are the mean, median, and mode.
The mean is the average of the values in a set of data. It is calculated by adding up all the values and then dividing by the number of values.
The median is the middle value in a set of data when the data is arranged in order from least to greatest. If there are two middle values, the median is the average of those two values.
The mode is the most frequent value in a set of data.
Correlation is a measure of the strength of the relationship between two variables. It is a number between -1 and 1, where -1 indicates a perfect negative correlation, 0 indicates no correlation, and 1 indicates a perfect positive correlation.
A measure of central tendency is a way of describing the central or typical value of a set of data, while correlation is a measure of the strength of the relationship between two variables. Therefore, correlation is not a measure of central tendency.
