Understanding Measures of Central Tendency

What is the primary purpose of measures of central tendency in data analysis?

• To summarize a set of data by identifying the central point

• To identify the highest and lowest values in a dataset

• To calculate the variance and standard deviation

• To determine the correlation between two variables
