Measures of Central Tendency

ADMS 2320: TERM TEST #1 PREP · Winter 2024 Chapter 4: Numerical Descriptive Techniques Measures of Central Tendency

Measures of Central Tendency summarize large sets of data with just one number, like an average. This could be the mean (the average you’re most familiar with), the median (the middle number), or the mode (the most frequently occurring number). These measures help us understand and communicate large sets of data more easily.
