Summary table 1

Question 1

NOMINAL level of measurement: descriptive statistics:

Answer 1

• Frequency table (with proportions/percentages)

- Mode

Question 2

NOMINAL level of measurement: graphical tools:

Answer 2

• Bar chart

- Pie chart

Question 3

ORDINAL level of measurement descriptive statistics:

Answer 3

• Frequency table (with proportions/percentages)
• Mode
• Median [and percentiles, quartiles, deciles]
• [Mean? Maybe but with caution]
• Range [min and max values]

Question 4

ORDINAL level of measurement: graphical tools:

Answer 4

• Bar chart
• Pie chart
• Histogram? maybe

Question 5

INTERVAL/RATIO level of measurement: descriptive statistics:

Answer 5

• Frequency table if FEW values [otherwise likely to be unwieldy - or, can group the values]
• Mode only if reasonable [if many observed values, likely to get many modes]
• Median [and percentiles, quartiles, deciles]
• Mean [and SD]
• Range [min and max values]

Question 6

INTERVAL/RATIO level of measurement: graphical tools:

Answer 6

• Histogram
• Box-plot
• Bar chart [but if many observed values, histogram will probably give a clearer summary]
