2 What is a line plot?  A line plot displays data along a number line.  Each x represents one number in the data.

3 Outlier  A number in a data set that is very different from the other numbers.

4 Here, x’s = houses with pets

5 Average Number of s  x x x x x x x___x___x_____x__________ s sent today  What is the average number of s sent today?  Remember to find the average : ADD and Divide  What is the range?  What is the mode?  What is the median?

6 What is the outlier here?

7 What is the Median? text pg. 226  The median is the middle number when the data are listed in order.  The number of raisins in our boxes:  10, 26, 26, 27, 30, 32, 32, 32, 34  x  30 is the median.

8 What is the mode?  The mode is the number or numbers that occur most often in the data.  10, 26, 26, 27, 30, 32, 32, 32, 34  The mode is 32.

9 What is the range?  The range is the difference between the greatest and the least number in the data.  10, 26, 26, 27, 30, 32, 32, 32, 34  The greatest number is 34. The least number is 10.  34 – 10 = 24. The range is 24.

10 What is the mean? Pg. 404  The mean is the average. It is found by adding all the numbers in a set and dividing by the number of values.  10, 25, 20, 5, 20  The sum is 75.  We added 5 numbers.  Divide 75 by 5.  The average or mean is 15.

11 Mean  The blocks  that are all  the same  height show  the average  or mean.

12 Practice at this interactive website.  esize/maths/activities/modemedianm ean.shtml esize/maths/activities/modemedianm ean.shtml

13 What is a bar graph? p 208  A bar graph is a graph using bars to show data.  Bar graphs can be vertical or horizontal.

14 Compare and Contrast

15 Parts of a bar graph  Scale: Numbers that show the units used on a graph are the scale.( The numbers on the graph.)  Interval: a number which is the difference between two consecutive numbers on the scale of a graph. (p. 208)  The interval is 5.  The graph must have labels!

16 Steps for creating a bar graph.  Choose a scale.  Draw and label the side and bottom of the graph.  Draw a bar on the graph for each piece of data.  Give the graph a title. The title shold describe the subject of the graph.

17 Make a bar graph.  /classic/bar_pie_data.asp?ChartType =bar /classic/bar_pie_data.asp?ChartType =bar  Y axis – vertical (up and down)  X axis – horizontal (across)
