Frequency Density and Histogram Analysis

The video tutorial explains how to complete a table and histogram using frequency density calculations. It covers the use of a formula to determine frequency density, calculates class width, and demonstrates how to work with frequencies. The tutorial also includes a section on reverse calculations and provides instructions for drawing the histogram.

What are the two methods mentioned for solving the problem?

• Counting squares and using a formula

• Using a calculator and guessing

• Drawing a graph and using a ruler

• Using a computer and a spreadsheet

What is placed at the top of the formula used in the video?

• Time

• Frequency density

• Class width

• Frequency

How is class width calculated for the interval 80 to 100?

• By subtracting 80 from 100

• By adding 80 and 100

• By multiplying 80 and 100

• By dividing 100 by 80
