statistics: Measures of Central Tendency
- Mode
- The value that is most common
- STRENGTH
- Normally unaffected by extreme scores and may give an idea of how often something is occurring
- WEAKNESS
- It is not a useful way of describing the data when it's bi-modal or more.
- Median
- Arrange scores in a set of data from lowest to highest and finding the middle score
- STRENGTH
- The median is less effected by extreme scores than the mean
- WEAKNESS
- It is not suited to being used with small sets of data especially if containing widely varying scores
- Mean
- Add all the scores in a set of data together and dividing by the total number of scores
- STRENGTH
- It makes use of all the values of the data- the mean can be said to be representative of all the data collected
- WEAKNESS
- Any rogue outliers can distort the mean making it untypical of the data set
- Sometimes the mean does not make sense in terms of the data set
