Question

question 5 (1 point)
which of these best estimates the standard deviation of points in a card game?
points in a card game
a 5 points
b 20 points
c 50 points
d 500 points

Explanation:

Step1: Recall standard - deviation concept

Standard deviation measures the amount of variation or dispersion of a set of values.

Step2: Observe data spread

The data points range from 490 to 510. Most of the data is clustered around 500, with values 490, 495, 505, 510 being the outliers. The spread is relatively small.

Step3: Estimate standard - deviation

A standard - deviation of 5 points seems reasonable as the values are mostly within 5 - 10 points of the central value (around 500). A value of 20, 50 or 500 points would be too large for this data set.

Answer:

A. 5 points
