What is a general method for adding a decimal with two decimal places to a decimal with three decimal places. give an example.

To add decimals, follow these steps:

Write down the numbers, one under the other, with the decimal points lined up.

Put in zeros so the numbers have the same length (see below for why that is OK)

Then add, using column addition, remembering to put the decimal point in the answer.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
