1. Descriptive statistics

2. Types of tables/graphs
Frequency table (tally chart)
Line graph
Pie chart
Bar chart
Histograms
Scatter diagram

3. Tally charts
Tally marks are used for counting things. These are used in content analyses and observations. They record the number of times something is seen.

4. Bar charts
Used to represent the data from frequency tables, mean scores or the totals.
The bars are kept separate from each other – different categories

5. Histogram Interval or ratio data.
There are no gaps between the columns to represent a continuous data set.
Data is linked

6. Line graph Alternative to histogram
These are used to show the results from two or more conditions at the same time.

7. Pie chart Used when we have %
Each segment represents a percentage of the total

8. Scatter diagram
Used with correlations where the relationship of two variables is summarised.
They illustrate the direction of the relationship (positive, negative or zero correlation) and can indicate the potential strength of the relationship.
For example, this scatter graph shows a positive correlation between ice cream sales and weather

9. Step 1: Identify the five different types of graphs Step 2: Place the correct pictures of each graph under the appropriate headings Step 3: Place the correct descriptions of each graph under the appropriate headings

10. ALL GRAPHS NEED:
Appropriate scales
Accurate plotting of data
Label X axis with ‘X’ and title (apart from pie chart)
Label Y axis with ‘Y’ and title (apart from pie chart)
Detailed title

11. Interpreting the data:
Using the examples you already have, tell me some information about what is displayed
Make reference to the title, both axes and the direction of the results in your answer.
