## Mean, Median, Mode, and Range

Data Set: 7, 9, 5, 2, 7

Mean: 7+9+5+2+7= 30/5= 6

Median: 2, 5, 7, 7, 9= 7

Mode: 7:2 9:1 5:1 = 7

Range: 9-2= 7

Answers: Mean=6 Median=7 Mode=7 Range=7

## Dot Plots Dot plots can help you identify the mean, mode, median, and range of the data. (click photo to zoom in) If you look at this example, you will be able to see that the values 8 and 9 occur most often, so 8 and 9 are the modes. If you add all the values together using the info on this graph, you will be able to find the mean. If you list all of the values in order, you will be able to find the mean. By looking at this graph, you can identify that the least value is 0 and the greatest value is 9, so 9 is the range. | ## Line Plots Line plots are the exact same thing as dot plots. (click photo to zoom in) The difference is that line plots use "x" instead of dots to show the occurrences. You can also find the mean, mode, median, and range using the information from the graph. | ## Box and Whisker Plots Box and whisker plots can help you find the inner quartile range, range, median, and upper and lower extremes. (click photo to zoom in) The line in the middle of the box is the median. The lines on the right and left side of the box are the values that show the first and third quartile. These values help you identify the inner quartile range. The inner quartile range shows the location of 50% of the data. The ends of the line that runs through the box shows the values that will help you identify the range and where the rest of the data is located. Box and whisker plots also help you compare spreads of data. |

## Closure

This is a lot of what I learned in this unit. The attachment is the same as last week but it covers a lot of what we learned in this unit. Thanks for watching and I hope you enjoyed viewing this reflection!
