To work out skewness and sorting, you will need to consider different statistical measures and techniques. Here are the steps to calculate skewness and sorting:
1. Skewness:
Skewness is a measure of the asymmetry of a distribution. It tells you if the data is skewed to the left or right. To calculate skewness, you can follow these steps:
- Calculate the mean (average) of the data set.
- Calculate the standard deviation of the data set.
- Calculate the third moment of the data set, which is the average of the cubed deviations from the mean.
- Divide the third moment by the cube of the standard deviation.
- The resulting value is the skewness of the data set. A positive skewness indicates a right-skewed distribution, while a negative skewness indicates a left-skewed distribution.
2. Sorting:
Sorting refers to arranging data in ascending or descending order. To sort data, follow these steps:
- Arrange the data in a list or table.
- Choose either ascending or descending order based on the requirements.
- Start comparing adjacent elements and swap them if they are not in the desired order.
- Continue this process until all the elements are in the desired order.
