Slide 5

Objective: To construct and analyze histograms.

Slide 6

Histograms At the end of this lesson you should be able to answer the following question. Why would you create a frequency table before you create a histogram?

Slide 7

Histograms A histogram is a type of bar graph used to display numerical data that has been organized into equal intervals.

Slide 8

Histograms Cost of Planes Number of Planes

Slide 9

Histograms How many remote control airplanes cost at least $100? Cost of Planes Number of Planes

Slide 10

Histograms How many remote control airplanes cost at least $100? 2 + 0 + 1 = 3 Cost of Planes Number of Planes

Slide 11

Histograms How many remote control airplanes cost less than $75? Cost of Planes Number of Planes

Slide 12

Histograms How many remote control airplanes cost less than $75? 9 + 7= 16 Cost of Planes Number of Planes

Slide 13

Histograms The histogram shows the wins for basketball league teams. How many teams won 31 games or more?

Slide 14

Histograms The histogram shows the wins for basketball league teams. How many teams won 31 games or more? 4 + 10 + 8 = 22

Slide 15

Histograms The histogram shows the wins for basketball league teams. How many teams won 40 games or less?

Slide 16

Histograms The histogram shows the wins for basketball league teams. How many teams won 40 games or less? 2 + 4 + 4 = 10

Slide 17

Histograms Histograms are an excellent way to show continuous data; such as weight, height, and how much time.

Slide 18

Histograms When the data is in categories ( such as favorite movies or countries), a bar graph is a better choice.
