Math Problem Statement

Given a table of class intervals and frequencies, find relevant statistical measures such as mean, median, mode, cumulative frequency, range, and variance.

Solution

The image you've provided shows a table with class intervals and frequencies. Here’s a breakdown of the dataThe image you've provided shows a table with class intervals and frequencies. Here’s a breakdown of the

  • Class Intervals: 0100 - 10, 102010 - 20, 203020 - 30, 304030 - 40
  • Frequencies: 10, 45, 12, 3

Would you like me to calculate any specific statistical measures, such as the mean, median, mode, or any other summary statistics?

Would you like me to calculate any specific statistical measures, such as the mean, median, mode, or any other summary statistics?


Here are some follow-up questions related to this

  1. Would you like to find the mean of this grouped frequency distribution?
  2. Do you need help finding the median or mode for these intervals?
  3. Are you interested in calculating the cumulative frequency for each class interval?
  4. Would you like to create a histogram or frequency polygon for this data?
  5. Are you interested in knowing the range and variance of this distribution?

Tip: For grouped data, calculating the midpoints of each interval is essential for finding the mean accurately.

Formulas

Mean = Σ(f * x) / N
Median = L + [(N/2 - CF) / f] * h
Mode = L + [(f1 - f0) / (2f1 - f0 - f2)] * h
Range = Highest class limit - Lowest class limit
Variance = Σ(f * (x - Mean)^2) / N
