Types of Graphs By: Mrs. Mowery
Histograms Definition --Histogram is a special type of bar graph that uses intervals of equal size.
Amount of Books Read by 6th Grade Students
Think about it… When would you need to create a histogram?
You could use a histogram to compare…The number of siblings a person has. The number of books read. The number of CD’s someone owns. The amount of pets someone has. The amount of money someone earns.
Steps for Creating a HistogramStep 1: Create your Survey Decide what you are going Survey or Chart. Record the data. Remember you need to survey something that can use intervals.
Steps for Creating a HistogramStep 2: Gather Data Divide the Data into equal sized intervals. Create a frequency table. Record tallies and count the frequency.
Number of CDs Number of People (Tally) Frequency 0-5 4 6-10 1 1 1 3 11-15
Steps for Creating a HistogramStep 3:Draw your histogram. Choose a vertical scale. Title the graph Label the horizontal axis and vertical axis.
Circle Graph Definition:Circle Graph is a graph in the shape of a circle that shows fractions/ percents. It is used to compare part to whole. Also known as the Pie Chart
Think about… When would you need to create a circle graph?
You could use a circle graph to compare/ show…Favorite team sport Favorite flavor of ice cream How you spend the hours of a day Monthly budget percentages
Steps for Creating a Circle GraphStep 1 : Create your Survey Decide what you are going to survey Make sure it is something that compares part to whole
Steps for Creating a Circle GraphStep 2: Gather Data Create a frequency table that includes: Choices, Fraction, Decimal, and Percents
Favorite Team Fraction Decimal Percent Bengal 12/20 0.60 60% Browns 8/20 0.40 40%
To go from a fraction to a decimal-Divide the numerator by the denominator. Example: 12 /
To go from a decimal to a percent- Multiply by 100.Ex: x 100 = 60 %
Steps for Creating a Circle GraphStep 3: Draw your circle graph Place a dot in the center. Estimate the fraction to shade. Include labels, percents, and an appropriate title.
Hints on Drawing a circle graph.Draw a dot in the center of the circle. Start with the easiest percent to graph. Ex: 25% = 1/4, 50% = 1/2, 75% = 3/4 Ex: 33% = 1/3, 67% = 2/3

Notes 51 Histograms.
Frequency Tables Histograms. Frequency-How often something happens. Frequency Table- A way to organize data in equal intervals. Histogram- Shows how frequently.
