Presentation and display of quantitative date

• 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
