Transcript of Histogram
A histogram is a graphical display of data using bars of different heights. A histogram is similar to a bar graph but it groups the data into ranges and frequencies.
The bars in a histogram, shouldn't have spaces in between them

Tools to make a histogram
1) Data- This is what your histogram is based off of.
2) Triple T-Chart- This helps you organize your data into ranges and helps to find the frequency.
How to make a histogram step by step
Step 1. Arrange the data into a triple t-chart
This is how the triple T-chart should look like:
Step 2. Make the scale. The Range goes on the X axis and the frequency goes on the Y axis.
A) Students must know how to calculate range and frequency with the given data using appropriate strategies.B) Students must know how to label the X axis in relation to the given data.
Step 3. Make your bars according to the range and
frequency. Make sure there are no spaces in between the bars.
Step 4. Add a title to your graph and label your
Question for the class:
These are the number of apples that fell off an apple tree each day over the course of 20 days:
X and Y axes.
Sum of the frequency, should
equal, the number of total data.

Jack recorded the weight of his German Shepherd each month over the course of a year.
These are his recordings:
66, 68, 73, 70, 72, 75, 73, 78, 80, 82, 81, 79
A) Create a triple t chart and use that to make
B) What do you think would happen too the data
if Jack had a smaller dog such as a Chihuahua?
C) Make an inference based on the mode
First, let's start with a Triple T-Chart.
Use the strategies that were taught to you and your own thoughts to make a histogram with this data.
