Mean, Median, and Mode: Familiarize yourself with measures of central tendency. Variance and Standard Deviation: Comprehend measures of dispersion. Having a strong grasp of these prerequisites will pave the way for a more comprehensive understanding of statistics and statistical analysis techniques. ...
Calculating the standard deviation of a dataset:The standard deviation is a measure of the amount of variation or dispersion in a dataset. It is calculated as the square root of the variance, which is the average of the squared differences from the mean. Using the math.sqrt() method, you ...
