The mean of the following series is ______. (rounded off to three decimal places) $0.01, 0.02, 0.03, \cdots \cdots, 1$
The question asks for the mean of the series: $0.01, 0.02, 0.03, \cdots \cdots, 1$. This is an arithmetic progression.
To find the mean of an arithmetic progression, we can use the formula:
$ \text{Mean} = \frac{\text{First Term} + \text{Last Term}}{2} $
$ \text{Mean} = \frac{0.01 + 1}{2} $
$ \text{Mean} = \frac{1.01}{2} $
$ \text{Mean} = 0.505 $
The question requires the answer rounded to three decimal places. The calculated mean $0.505$ is already in this format.
The mean of the series is 0.505.
A data set is given to be $[1, 2, 0, -1, -3, 1, 2, 0, 1]$.
