MHB Construct a frequency distribution using 5 classes

Click For Summary
The discussion focuses on constructing a frequency distribution for the time spent reading a political blog, using a dataset of minutes ranging from 0 to 49. Participants suggest dividing the data into five equal classes: 0-9, 10-19, 20-29, 30-39, and 40-49. The frequency distribution table includes calculations for frequency, midpoints, relative frequencies, and cumulative frequencies. The class with the greatest frequency is identified as 0-9, while the least frequency class is 40-49. This method effectively summarizes the reading time data into a clear distribution format.

How do you know what the classes are?

Hi rihnavy! Welcome to MHB! ;)

By dividing the range into 5 equal parts.
The minimum is 0 and the maximum is 49.
So pick 0-9, 10-19, 20-29, 30-39, 40-49.
 

Thread 'Area of Overlapping Squares'

Here is a little puzzle from the book 100 Geometric Games by Pierre Berloquin. The side of a small square is one meter long and the side of a larger square one and a half meters long. One vertex of the large square is at the center of the small square. The side of the large square cuts two sides of the small square into one- third parts and two-thirds parts. What is the area where the squares overlap?
