More Ways to Represent Data

Line Graphs

1. What does the line graph show us?

2. How frequently were measurements taken?

3. Why does it make sense to connect the dots with lines?

4. If you see a graph with a connected line like this, what does it imply about the data?

Scatterplots

1. What information does the scatterplot show us?

2. Why does it not make sense to connect the dots?

3. Even if we don't connect the dots, can we draw a conclusion from the picture?

Positive, Negative, and no Association

Given a scatterplot the points either have positive association (a general positive slope),

negative association (a general negative slope), or no association (can't even guess at a trend

line).

Multiple Line Graphs

1. What information does the line graph show us?

2. Why is it useful to have the multiple line graphs in one picture?

3. Why does it make sense to connect the dots like this?

How the heck do we know when to use what????

See p.578 in the book, then for each type of display give an example of a set of data where you would need that particular type of display.

Bar graph

Histograms

Stem and leaf plot

Scatterplot
