Tables Collecting data • You can collect data (information) from other people using polls and surveys. • Scientists collect data from experiments. • Tables and graphs help us organize and interpret collected information. The mean is the average of a set of numbers. To find the mean, add all the numbers in the set and divide the sum by the number of items in the set. The median is the middle number when the data are in numerical order. The mode is the number that occurs most often in a set of data.

A bar graph is one way of showing data that can be counted. Each segment in a circle graph represents a fraction of a set of data. A line graph presents a set of data collected over time using line segments. Months Months Number of bikes sold Number of Bikes A stem-and-leaf plot shows data arranged by place value. 3 + 5 + 2 + 6 + 4 Line Graph Circle Graph Bar Graph Stem–and–Leaf Plot Ranger Bike Tally Total Outdoor Tourist Starburst Mountain RangerOutdoorT ourist Starburst Mountain 0 1 2 3 4 5 6 7 8 9 10 Total 20 10 2 1 4 3 10 20 30 40 50 60 10 20 30 40 50 60 January F ebruaryM ar ch M ay A pril June July A ugust 15, 20, 28, 31, 35, 46, 49, 52 (arranged from least to greatest) Stem (tens digit) Leaf (ones digit) Mountain (10 bikes) 5 08 15 69 2 1 2 3 4 5 Outdoor (4 bikes) Ranger (3 bikes) Starburst Tourist(1 bike) To find the number of gears of the Starburst bike, look across the Starburst row until it meets the Gear column.
