The variance and the standard deviation are related by the fact that the square root of the variance is
equal to the standard deviation. Suppose the variance of the time it takes to complete a bachelor’s degree
is 1.6 . Find the standard deviation. Round your answer to four decimal places.

To find the standard deviation, you simply take the square root of the variance. In this case, the variance is 1.6, so the standard deviation is √1.6. Calculating this gives you approximately 1.2649 when rounded to four decimal places. So, the standard deviation is 1.2649.

Understanding these concepts is like stirring a pot of knowledge! The variance provides insight into the spread of your data, while the standard deviation gives you a more intuitive grasp of how data points deviate from the mean in the same units as the original data. This makes it easier to interpret and apply in various real-life scenarios, like assessing student performance or testing efficiency in different fields.
