- Measures of Central Tendency
- Mean
- The arithmetic average
- total all the values in the data set and divide by the number of values
- Strengths
- includes all numbers in a data set
- Weaknesses
- anomalies can inflate or deflate the average
- Median
- the middle value of a data set
- Numerically order the values (lowest to highest) and find the middle value
- Strengths
- not affected by extreme values
- Weaknesses
- does not use all the numbers in the dataset
- with an even set of data, median may not be an original score (decimal points)
- cannot be further used in mathematical calculation
- Mode
- the most common value
- how many of one value is in a data set
- Strengths
- Useful when using a behaviour checklist or nominal data
- unaffected by anomalies
- easy to calculate
- Weaknesses
- does not represent all data in the data set
- Mean
