Graphs + Tables

Tables

What are the types of tables + their definitions?

• Raw data table = a record of individual data points collected from Ps

• Frequency table = a log of the frequency of observations of behavioural categories → tally charts

Graphs

What goes on the the X and Y axis’s of a graph?

• X = IV

• Y = DV

Graphs

What are the types of graphs?

• Bar chart

• Scattergram

• Histogram

• Line graphs

Graphs

What are bar charts?

Summarises the frequency of NOMINAL data

Graphs

What are scattergrams?

• Show relationship b/w 2 co-variables

• Each point plotted represents two variables/measurements of the same P

• Either variable can go on either axes

Graphs

What are histograms?

• Displays the frequency of continuous numerical data (eg: test scores, age group, time scales, weight, height, income level

• Bars TOUCH

Graphs

What are line-graphs?

• Allow for the display and comparison of two sets of continuous data on the same graph

Graphs

What graph would you use for nominal data?

Bar chart

Graphs

What graph would you use for ordinal or interval data?

• Line graph

• Histogram

Graphs

What graph would you use for correlational data?

Scattergram

Graphs

What information/things should be included for a graph question?

• Appropriate title with the operationalised DV + both conditions of the IV/relationship

• Labelled axis (w/ operationalised variables)

• Accurately plotted data

• Appropriate scale (remember to write 0)
