Lesson 1 -2 Creating Dot Plots

Learning Targets I can create dot plots and use median and mode to match plots with statistical questions.

Definitions Define the following words in your math journal: o Dot plot o Data landmark o Maximum o Minimum o Distribution o Variability o Median o Mode

Math Message Complete the Math Message problems on journal page 5.

Math Message Follow Up Cut 1 copy of page 7 into 5 pieces Complete the statements at the top of journal page 6. DO NOT SHARE YOUR ANSWERS!! Do not write ANYTHING on your paper Do not go on to the next question until I tell you to!!

Statistical Questions How many students are in a typical class is our school? o How could we find the answer to that question? o Why is this a statistical question? How could we rephrase the Math Message questions into statistical questions? o How many hours of television shows do students in our class watch each week?

Group Work Each group complete the following: o List the data in order from least to greatest to make it easier to plot o Using markers and the large sheet of paper, draw a dot plot to represent the data. o Write the envelope number on the line plot.

Discussion Look at the charts and discuss with your partner… o Which chart to do you believe matches the statistical questions that we just created? Why is the number of data points shown on each dot plot the same? What information in the dot plots did you use to match them with the questions? How did the largest number (maximum) and the smallest number (minimum) and the distance between them (range) help you make decisions?

Discussion How the data is spread out—where it clumps and where there is no points—is sometimes called the data distribution. The variability describes how spread out the data is. How can the shape of the data distribution help you match each dot plot to a statement? Which statement was easiest to identify? Most difficult? Why?

With a partner… Estimate and solve the multiplication problems on page 7 in your journal. Let’s look at traditional multiplication. Homework: o Study Link 1 -2 o Math Boxes 1 -2
