Descriptive Statistics (Measures of Central Tendency (Mode - The most…

- - - - Unaffected by extreme scores
      - It can be used with nominal data, and it provides information about frequency
    - - Not a sensitive measure as not all the values are represented as it ignores outliers but these are still part of the data set
      - The data may have several modes (2 modes = bi-model etc.)
  - - - Makes use of all data but isn't as effected by extreme scores as compared to the mean
      - It can be used with ordinal data
    - - Not as sensitive as the mean as not all the values are reflected
      - More open to bias from extreme scores than the mode
  - - - It makes use of all the numbers in the data set, making it a sensitive measure
      - Appropriate to use for any set of data
    - - It is affected by extreme scores and can misrepresent the numbers as a result
      - It isn't useful for small sets of data
- - - - It's easy to calculate and shows extreme values
    - - It's affected by extreme values and doesn't take into account he number of observations in the data set
      - It doesn't give information on whether the scores are clustered around the mean or spread out
  - - - Gives a more precise measure of dispersion than the range as all values are taken into account
      - Provides information on whether the scores are clustered around the mean or spread out
    - - It is more complicated to calculate than the range
      - May be misleading if the distribution of data is skewed
