1. Line Plots, Frequency Tables and Histograms

2. Line Plots, Histograms and Frequency Tables
Frequency - Represents the number of times something
happens or occurs.
Line Plots – Is a number line with marks or dots that show
how frequently something occurs.
Histogram - Is like a bar graph that shows how much data
falls within given intervals. Histograms look similar to bar
graphs except:
Histograms focus on one topic using descriptions/intervals while bar graphs compare category totals.
You do not leave spaces between the bars on a histogram.
Frequency Tables - Is a table that is used to gather the
number of data that falls within each interval. The information
gathered in a frequency table is used to create a histogram.

3. Line Plots Example 1: Given the following
data, let’s create a line plot.
Mileage ran by Mr. Lee’s students:
8, 3, 5, 6, 7, 8, 5, 5, 3, 6, 10, 7, 5
Number of Miles Ran

4. Histograms and Frequency Tables
Example 1: Given the following
data, let’s create a frequency table
and histogram.
Mrs. Choe’s students fingerprint
patterns:
whorl, loop, loop, loop, loop, arch,
loop, whorl, arch, loop, arch, loop,
arch, whorl

Example 2: Given the following
data, let’s create a frequency table
and histogram.
Points scored by the New York
Giants during the season:
15, 13, 27, 18, 31, 13, 20, 13, 27, 38, 22,

6. Analyzing Histograms
Answer the following questions about the histogram below.
1.) How many people did between 11 and 20 jumping jacks?
2.) What interval contains the most people?
3.) The results of how many people are included in this histogram?
4.) What is one piece of information that you cannot answer based on the histogram?
