LESSON 3 Analyzing Data

Which Graph Is Which?

Professor Peabody collected three sets of survey data at Bessie Coleman School.

The number of pockets on the clothes of 15 students in a classroom.
The number of pockets on the clothes of the same 15 students as they played on the playground. (Each student wore a jacket outside.)
The number of pockets on the clothes of 31 students in a different classroom.

For each set of data Professor Peabody drew a picture, recorded the data in a table, and made a graph. Just as he finished graphing the data, he remembered that he had to get back to his lab to check on another experiment. When he got back, he discovered that he had left his pictures and data tables at Bessie Coleman School. All Professor Peabody had at his lab were his graphs. But when he looked at his graphs, he saw that he had forgotten to write titles on them.
