How did the CYUQs go yesterday?

Work with your group to create a dot plot that displays data from our class' survey.

Model how to create a histogram with ranges of ten based on ages at a graduation party (10 items) 12, 30, 37, 22, 41, 45, 5, 35, 38, 13

What is the frequency of grades between 60 and 80?

How many students have shoe sizes between 10 and 11?

Work with your group to create a histogram for the following data:

Points scored in a weekend tournament (15 values) 7, 42, 19, 33, 31, 48, 25, 4, 39, 21, 2, 34, 36, 28, 9

A histogram is a type of bar graph that organizes data into equal buckets (ranges). In addition to helping us to see the data, it makes it easy to see the frequency distribution.

To create a histogram:

1. Based on the data, determine the size of the buckets (ranges): 5, 10, 15, ... ?

2. Setup a graph with the buckets (ranges) on the x-axis and the frequency on the y-axis (remember to write labels)

3. Place each data point in the correct bucket (range)

Bar graph vs histogram:

1. In your notebook, make meaningful notes for your forgetful selves

2. CYUQs → Do in your notebook. You chose where you want to start. Check your work with the students around you and if you need help, get help. And if someone else needs help, give help.
