Q 108.

Question

You have data on the weights in grams of $5$ baby pythons. The mean weight is 31.8 and the standard deviation of the weights is $2.39$ . The correct units for the standard deviation are

(a) no units—it’s just a number.

(b) grams.

(d) pythons.

(e) pythons squared

Step-by-Step Solution

Verified

Answer

The correct option is (b) grams.

1Step 1: the given information

The number of baby pythons is $5$ .The mean weight is $31.8$ and standard deviation of the weights is $2.39$ .

2Step 2: Concept

Statistical Measures are a descriptive-analytical technique that provides an overview of a data set's properties.

3Step 3: Explanation

The right unit for the standard deviation would be the same as the unit of measurement for the original data if the data on the weights in grams of $5$ newborn pythons is given. So, the grams is the correct answer.
