Homeroom Survey:Number of Children in the House

A line plot uses an "x" or another symbol to show data on a number line.

Homeroom Survey:Number of Children in the House

A dot plot is the same as a line plot,but it uses dots instead of x's.


Practice Question:

Using the line plot, calculate the difference between the mean and the median.

HistogramsUse bars to show data range or interval data. (There is no gap between bars.)

This histogram displays the number of people in each age group who attended the play.

For example, from this graph, I can tell that 50% of those who attended were over the age of 15.

How tall are you (in inches)?Box and Whisker Plot steps:1) Put data in order

2) Draw brackets at minimum and maximum numbers

3) Find median and draw a large line above it

4) Find the median of each half; these will be your quartiles. Draw a box between them.

Statistics Project - Due Friday

1) Collect Data:

Ask twenty people a survey question. (It is okay to use one of the ones we used in class or a new one, but it must be quantitative.)

2) Find the mean, median, mode and range of the data.

3) Choose a graph from your foldable to represent the data.

4) Show all of this on construction paper, poster board or booklet.

Brownie Points: Find Mean Absolute Deviation of your data
