1 Chapter 10 Section 1, 3-4

2 Warm-Up List the data in order from least to greatest. 1.) 23, 45, 61, 87, 91, 16, 22, 52 2.) 4.1, 4.2, 4.13, 4.15, ) 132, 116, 108, 191, 125, ) 7.25, 7.3, 7.08, 7.9, 7.62

3 Warm-Up 2 List the data in order from least to greatest. 1.) 32, 31, 34, 30, 13, 33 2.) 121, 119, 137, 125, ) 11.1, 10.9, 11.3, 11.5, ) -4, -5, 0, -1, 2, -3

4 Notes A frequency table is a table that lists each item in a data set with the number of times the item occurs A line plot is a graph that shows the shape of a data set by stacking X’s above each data value on a number line A histogram is a bar graph with not spaces between the bars

5 Example(s) Make a frequency table of each set of data. 1.) tickets sold per day

6 Example(s) Make a frequency table of each set of data. 2.) ages of students

7 Example(s) Make a line plot of each set of data. 3.) number of plants sold per person

8 Warm-Up Find the median of each set of data. 1.) 24, 42, 51, 25, 63 2.) 38, 30, 26, 20, 32, 48 3.) 2.1, 3.2, 4.8, 5.6, 3.1, ) 5.8, 6.9, 7.4, 3.9, 6.4

9 Chapter 11 Section 3 Notes A stem-and-leaf plot is a graph that uses the digits of each number to show the shape of the data A box-and-whisker plot is a graph that summarizes a data set along a number line

10 Steps for making a stem-and-leaf plot Step 1: Choose the stems. The stems are made using the values in the ones place Step 2: Find the leaves. The leaves are the values in the tenth place. ***i.e. Using the number 23, 2 would be the stem and 3 would be the leaf Step 3: Order the leaves from least to greatest. A key explains what your stems and leaves represent. Add a title.

11 Example Ex. 1) Draw a stem-and-leaf plot for the heights of giant sunflowers

12 Steps for making a box-and-whisker plot Step 1: Order the data from least to greatest Step 2: Find the middle quartile by finding the median of the entire data set.(The median divides the data into two parts Step 3: Find the lower quartile by finding the median of the lower parts Step 4: Find the upper quartile by finding the median of the upper parts Step 5: Find the lowest and highest value of the data set

13 Example Ex. 2) Make a box-and-whisker plot for each set of data. Number of customers at a coffee house
