OBJECTIVE I will use tables and graphs to organize and read data.

Most Watched Sports Per Year (in millions of viewers) Using a Table The following table shows the number of viewers (in millions) for the four most watched sports.

Most Watched Sports Per Year (in millions of viewers) Using a Table In what 5-year period did total viewing decrease the most? Add two rows (total and change) Most Watched Sports Per Year (in millions of viewers) YEAR 1990 1995 2000 2005 Total 640.7 627.6 622.0 624.2 Change - -13.1 -5.6 2.2 The total number of sports viewers decreased most from 1990 to 1995.

Using a Bar Graph to Organize Data Bar Graph - one way to organize data in which vertical or horizontal bars represent a number for each category (used when there are categories)

Using a Bar Graph to Organize Data What was misleading about the previous bar graph? The Scale

Average Cost of Making a Movie (millions of dollars) Making a Line Graph Average Cost of Making a Movie (millions of dollars) Year 1983 1984 1985 1986 1987 1988 1989 1990 1991 1992 Average Cost ($) 11.8 14.0 16.7 17.5 20.0 18.1 23.3 26.8 26.1 29.9

Making a Line Graph Line Graph - used to organize data, typically to show change in data over time

Questions In which years did the average cost decrease from the previous year? In which year did the average cost decrease the most from the previous year? 1988, 1991 1988
