• what goes on the y-axis of a raw score table

  the different conditions
• what is a descriptive statistics table used for


  what the raw scores are converted into
• what is on the x-axis of a descriptive table

  conditions
• what is on the y-axis of a descriptive table

  the descriptive statistics
• what is a bar chart used for

  to show the difference in mean values, when data is divided into categories
• what goes on the x-axis of a bar chart

  conditions
• what goes on the y-axis of a bar chart

  performance scores/results
• what is a scattergram used for


  correlation studies, when showing an association between co-variables
• what goes on the x-axis of a scattergram

• what is a histogram used for

  to show data is continous
• what is on the x-axis of a histogram


  equal sized intervals from a single category
• what is on the y-axis of a histogram

  the frequency of each interval
• what is a line graph used for

  to show data is continuous & how something changes in value
• what is on the x-axis of a line graph

  independent variable
• what is on the y-axis of a line graph

  dependant variable
• what is normal distribution

  symmetrical spread of frequency data, forms a bell-shaped pattern w/ the mode,median & mean are all at the highest peak
• what is skewed distribution

  spread of frequency data that's not symmetrical, data is clustered at one end
• what is a positive skew


  where the long tail is on the right side of the peak, most distribution is concentrated on the left
• what is a negative skew

  where the long tail is on the left side of the peak, most distribution is concentrated on the right
