ID - Representation of Data (Lesson)

Representation of Data

Let's practice what we've learned. This table lists the total number of home runs hit at home games by each baseball team in a specific region: 

Team	Home Runs	Team	Home Runs
County West High	24	Jackson High	19
Liberty High	25	South County High	20
Cardinal High	18	Falcon High	22
County East High	21	North County High	20
Hillside High	22	Eastwood High	14

Find the 5 measures of central tendency that represent the data: Minimum, First Quartile, Median, Third Quartile, Maximum.

We can take that data and make a dot plot to represent the scores. A dot plot is a way to display a distribution of data where each data value is shown as a dot or mark above a number line. The dot plot below shows the distribution of the baseball team's home runs.

Another way to represent data is by a histogram. A histogram is a way to display data as a bar graph. Watch this video to practice constructing a histogram. The class width of a histogram is the width of each bar in a histogram.
