Show the data we collected. Read the data out loud (to emphasize that it doesn't make sense when read out loud)

Informally re-survey and record the data in a dot plot. As them what the min. max. and most is. Emphasize that this is much easier to "see"

How many people were surveyed? How many people have 3 pets? How many have 1 pet?

Make a dot plot that shows the number of siblings. Identify the min, max and most.

Make a dot plot that shows the number of boxes sold. Identify the min, max and most.

A dot plot is a type of graph that is based on a number line. Each dot represents an individual data point. It makes it easier to see the data.

How to make a dot plot (a.k.a line plot):

1. Identify min. and max. (range)

2. Create a number line that represents the range of the data

3. For each data point, make a dot (or x) -- neatly spaced -- above the number

4. When finished, count the number of items in the data set and verify that you made the number of dots

1. Make notes for your forgetful selves

2. In your notebook, use the data sets below to create a dot plot. Then identify the min, max, and most.

A. Daily high temperatures: 71, 72, 74, 72, 72, 68, 71, 67, 68, 71, 68, 72, 76, 75, 72, 73, 68, 69, 69, 73, 74, 76, 72, 74

B. Number of tornadoes: 0, 0, 2, 1, 0, 1, 1, 0, 2, 1, 0, 0, 6, 0, 0

C. Length of summer camps in days: 7, 7, 12, 10, 5, 10, 5, 7, 10, 9, 7, 9, 6, 10, 5, 8, 7, 8

D. Estimates of room lengths: 10, 13, 15, 16, 17, 11, 13, 15, 16, 17, 12, 14, 15, 16, 18, 12, 14, 15, 17, 18, 13, 14, 15, 17, 25

3. When you don't understand, look at textbook examples (review the pages prior to the CYUQs) or search
