Which of the following describes measures of tendency?

Which of the following describes measures of tendency?

• A. Standard deviation, range, and variance
• B. Mean, mode, and median
• C. The difference between the highest and lowest values
• D. Types of graphical representation of data

Answer: (B)

Measures of central tendency are statistical measures that describe the center point or typical value of a dataset. The mean, mode, and median are the three primary measures used to convey this information. The mean is calculated by summing all values in a dataset and then dividing by the number of values, representing the arithmetic average. The median is the middle value when data points are arranged in order, providing a measure that is less affected by outliers than the mean. The mode, on the other hand, is the value that occurs most frequently in the dataset, indicating the most common observation. Together, these three measures provide a comprehensive view of the central location of data, effectively summarizing the dataset's overall behavior. This distinguishes them from standard deviation, range, and variance, which are measures of variability, and from graphical representations, which are visual tools for displaying data rather than summarizing it statistically.
