Data Analysis

When you collect data for an analysis or a report, it is important to organize the information so that it is easy to read and work with. One way to organize data is in a chart or table.

During the first week of April, Mark recorded information about the weather in the city of Milton.

Monday: 43°F high temperature; 34°F low temperature; cloudy; 0.1 inches rain
Tuesday: 55°F high temperature; 42°F low temperature; partly cloudy; no precipitation
Wednesday: 59°F high temperature; 45°F low temperature; sunny; no precipitation
Thursday: 62°F high temperature; 49°F low temperature; sunny; no precipitation
Friday: 54°F high temperature; 44°F low temperature; partly cloudy; no precipitation
Saturday: 52°F high temperature; 41°F low temperature; cloudy; 0.2 inches rain
Sunday: 52°F high temperature; 43°F low temperature; cloudy; trace of rain

If you organize this information in a weather chart, it will be easier to read and compare the data for different days.
