  • Tables can be used to present key descriptive statistics for a data set, such as mean values and standard deviation values for each condition within a psychological investigation
  • Presenting data in tables allows for easy comparison of important values without the need for data interpretation
  • Scattergram:
    • Shows the correlation between two sets of data by plotting points for each pair of scores
    • Indicates the degree and direction of the correlation between the co-variables, with one variable on the X-axis and the other on the Y-axis
    • Positive correlation: shows an upward trend where as one variable increases, so does the other
    • Negative correlation: shows a trend in the opposite direction where as one variable increases, the other decreases
    • Zero correlation: no distinct relationship shown between the two variables
    • Individual participant marks randomly appear on the scattergram
  • Bar charts:
    • Used to show frequency data for discrete variables
    • Plot mean scores separately for different conditions (e.g., A, B, C, D, E)
    • Histogram: similar to a bar chart but bars touch each other, indicating continuous data
    • Y-axis on a histogram represents frequency, while on a bar chart it represents value
