| Strengths of using mean? | -Makes use of all values
-Good for interval data |
| Limitation of using mean? | -It can be influeced by outliers, so it will be unrepresentative |
| Strength of using mode? | Used for norminal data (collected in categories) |
| Limitation of using mode? | Not useful when there are several modes |
| Strengths of using median? | -Not affected by extreme scores
-Good for ordinal data |
| Limitation of using median? | No as sensitive as mean, doesn't use all data |
| Strength of range? | Easy to calculate |
| Limitations of using range? | -Affected by extreme values
-Doesn't take into account all data |
| Strength of Standard deviation? | Precise measurement where all peices of data is taken into account |
| Limitations of Standard deviation? | -Difficult to calcualte
-Affected by extreme scores |
| What is norminal data? | Data that is formed by categories |
| What is ordinal data? | Represented through ranking form (1 to 10 eg) |
| What is intrval data? | Numeric scales that are precise units that are defined by size |
