What is mean median and mode?
The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set.
The median is the middle value when a data set is ordered from least to greatest.
The mode is the number that occurs most often in a data set.

Which central tendency is best?
The mean is the most frequently used measure of central tendency because it uses all values in the data set to give you an average. For data from skewed distributions, the median is better than the mean because it isn’t influenced by extremely large values.
What are the characteristics of a good measure of central tendency?
Explanation: it should be Well defined and rigid. it should be easy to understand and calculate. it should be based on all the observations of the data. it should be suitable for further algebraic operations. it should be a stable measure.More items…•

What is the central tendency effect?
Central tendency bias (sometimes called central tendency error) is a tendency for a rater to place most items in the middle of a rating scale. For example, on a 10 point scale, a manager might place most of his employees in the middle (4-7), with a few people getting high(8-10) or low(1-3) rated performances.

What does the median tell you?
The median provides a helpful measure of the centre of a dataset. By comparing the median to the mean, you can get an idea of the distribution of a dataset. When the mean and the median are the same, the dataset is more or less evenly distributed from the lowest to highest values.
