Creating Histogram

​To build a histogram, we need a few things...

• We need to figure out how wide each interval will be. We will use this to start organizing our data.

• Organize data within intervals by using a frequency table.

• Put all of this together in a beautiful histogram!

Rad

Math Response

For this histogram, we are going to use 6 intervals. Let's use the range (70.5) to determine the interval width. We will need to round to the nearest whole number.

Correct Answer: 12

Now that we got started with our frequency table, let's finish it out. Remember each interval is 12 mm wide. Frequency means how many times a number occurs in that interval.

​Your frequency table should look something like this. Write these values down on some paper because we will need this to draw our histogram in the next slide.

Draw

Use this empty graph to create your histogram with the information from the frequency table that you wrote down. It is OK if it is a little messy! Do your best :)

The data shows the number of Snapchats sent by 7th graders in one day:

99, 97, 94, 88, 84, 81, 80, 77, 71, 63, 60, 54

Use this to fill out the frequency table!
