Organizing Data (pages 22-24)

1. Circle the letters of tools that scientists use to organize their data.a. the Internet b. newspapersc. tables d. graphs

2. The simplest way to organize data is to present them in a(n)

3. Circle the letter of the place on a line graph where the manipulatedvariable is generally plotted.a. the y-axis b. the risec. the x-axis d. the run

4. On a line graph, the ratio of the change in the y-variable to thecorresponding change in the x-variable is called the line's

5. Circle the letters of the relationships that are direct proportions.a. distance traveled versus time at a constant speedb. the mass of a substance versus its volumec. the time to travel a given distance versus average speedd. the number of fingers in your classroom versus the number

of people
