Exploring Histograms and Frequency Tables

This video tutorial explains histograms, highlighting their differences from bar graphs. It covers how to interpret data using frequency tables and convert them into histograms. The tutorial provides examples using plant height data and random data collected from a store visit. It guides viewers through organizing data into frequency tables and creating histograms, emphasizing the importance of understanding data ranges and frequencies.

What is the main difference between a histogram and a bar graph?

• Bar graphs show frequency tables.

• Histograms show categorical data.

• Bar graphs show ranges of numbers.

• Histograms show ranges of numbers.

What type of data is best represented by a histogram?

• Categorical data

• Numerical ranges

• Qualitative data

• Individual data points
