Answer: i hope this helps :)

Explanation:

The reason dividing by n-1 corrects the bias is because we are using the sample mean, instead of the population mean, to calculate the variance. Since the sample mean is based on the data, it will get drawn toward the center of mass for the data. In other words, using the sample mean to calculate the variance is too specific to the dataset.
