How to fill out measures of central tendency

How to fill out measures of central tendency:

1. Identify the data set for which you want to calculate measures of central tendency.
2. Determine whether your data set is discrete or continuous. Discrete data consists of distinct numbers, while continuous data includes a range of values.
3. Calculate the mean, which is the sum of all the values divided by the total number of values in the data set. This measure gives an average value and is suitable for continuous data.
4. Calculate the median, which is the middle value in a data set when it is arranged in ascending or descending order. If there is an even number of values, take the average of the two middle values. The median is useful for data sets that may have outliers or extreme values.
5. Calculate the mode, which represents the value(s) that occur most frequently in the data set. There can be multiple modes or no mode at all.
6. Calculate other measures of central tendency if necessary, such as the geometric mean (for data involving ratios), weighted mean (if different values have different importance), or harmonic mean (for rates or ratios).
