Miss Arnold- Pass around height sheet!


What do you know about

What do you know about

  • bar graph?

  • double bar graph?

  • Histogram?


Bar graph

Bar Graph

  • A bar graph can be used to display and compare data

  • The scale should include all the data values and be easily divided into equal intervals.


Double bar graph

Double Bar Graph

  • Can be used to compare two related sets of data


Histogram

Histogram

  • Histogram is a bar graph that shows the frequency of data within equal intervals.

  • There is no space in between the bars.


How to make a histogram

How to make a histogram?


I can create histograms

The table below shows the number of hours students watch TV in one week Make a histogram of all the data.


Step 1

Step 1

  • Make a frequency table of the data. Be sure to use equal intervals


Step 2

Step 2

  • Choose an appropriate scale and interval for the vertical axis. The greatest value on the scale should be at least as great as the greatest frequency.


Step 3

Step 3

  • Draw a bar for each interval. The height of the bar is the frequency for that interval. Bars must touch but not overlap.

  • Label the axes and give the graph title


What can we interpret from this graph

What can we interpret from this graph?

Most students watch ____ hours of TV.

4-6


How many students were surveyed

How many students were surveyed?

I hope you didn’t say 20 or 17.

It’s all of the students….look back at the number of frequency's and add those up….to get 48 students.

Let s make a histogram of our heights in feet inches

Let’s make a histogram of our heights, in feet & inches.
