The variance of the data set with 10 numbers is 12. what is the standard deviation of the data set? 1.2 3.46 6 144
The standard deviation is the square root of the variance. Therefore, the standard deviation of the data set is √12, which is approximately 3.46.
To find the standard deviation of a data set, you need to take the square root of the variance.
The variance is given as 12. Taking the square root of 12 gives you:
√12 = 3.46
Therefore, the correct answer is 3.46.
To find the standard deviation of a data set, you need to take the square root of the variance. In this case, the given variance is 12.
To calculate the standard deviation, follow these steps:
1. Take the square root of the variance.
√12 = 3.464101615
2. Round the result to an appropriate decimal place based on the given options.
The options provided are: 1.2, 3.46, 6, and 144.
The correct answer is 3.46.
