One-variable data: distributions and measures of center and spread – Mean from Frequency Table

  • Hard, Problem-solving and Data Analysis
This guide demonstrates how to calculate the mean of a data set represented in a frequency table using Desmos. It breaks down the process of finding the mean using a table format, showing how to multiply frequencies by data points and then calculate the average. This method helps visualize and understand the concept of weighted average, where each data point's contribution to the mean is proportional to its frequency.
