PRESENTATION OF QUALITATIVE DATA

• Tables:

  • Presents quantitative data in a summary format.
  • Do not show raw scores, but instead show descriptive statistics
• Scatter graph:

  • Shows the relationship between 2 sets of data
  • Indicates the strength / direction of the correlation
  • Cannot establish cause / effect
• Histograms:

  • Continuous data (e.g. age). 
  • There should be no space between the bars, because the data is continuous
• Bar chart:

  • Shows frequency data for discrete (separate) variables. 
  • For example, bar charts are used to plot mean scores for conditions A & B separately.
• Normal Distribution:

  • MEAN , MEDIAN & MODE at the CENTRE
  • SYMMETRICAL

  
• Positive Skew:

  • TAIL points to the RIGHT
  • Mode- always at the HIGHEST point (most FREQUENT)
  • MEAN is GREATER than the MEDIAN (look at X-AXIS)

  
• Negative Skew:

  • TAIL points to the LEFT
  • Mode- always at the HIGHEST point (most FREQUENT)
  • MEDIAN is GREATER than the MEAN (look at X-AXIS)
