75th percentile - it is location on the data set. Hence it is neither central tendency nor a measure of variability

coefficient of variation
is defined as the ratio of the standard deviation to the mean

Hence standard deviation measures the spread , so it also becomes the measure of spread

1st quartile
it is location on the data set. Hence it is neither central tendency nor a measure of variability

Median absolute deviation
is a robust measure of the variability of a univariate sample of quantitative data
It is basically calculated as deviation from the mean value , hence a measure of spread

5the percentile
it is location on the data set. Hence it is neither central tendency nor a measure of variability. The 5th percentile of dataset

minimum
it is location on the data set. Hence it is neither central tendency nor a measure of variability . The minimum value of the dataset

Discussion: Central Tendency and Variability Understanding descriptive statistics and their variability is a fundamental aspect of statistical analysis. On their own, descriptive statistics tell us how frequently an observation occurs, what is considered “average”, and how far data in our sample deviate from being “average.” With descriptive statistics, we are able to provide a summary of characteristics from both large and small datasets. In addition to the valuable information they provide on their own, measures of central tendency and variability...
