73. Skewness

Lecture Resource: Exercise: Exercise solution: After exploring the measures of central tendency Let’s move on to the measures of asymmetry. The most commonly used tool to measure a symmetry is skewness. This is the formula to calculate it almost always you will use software that performs the calculation for you. So in this lesson we will not get into the computation but rather the meaning of skewness so skewness indicates whether the observations in a dataset are concentrated on one side. This can be confusing at the beginning. So an example is in place remember frequency distribution tables from previous lectures. Here we have three data sets and the resp
