Answer:
Option 2 - Standard deviation
Explanation:
To find : Which measure of dispersion indicates the extent to which each individual score in a data set varies from the mean of that set?
Solution :
Standard deviation is defined as,
- It is a mathematical measure that is used to evaluate the difference between the mean value of a set of number and each value in the group.
- It is calculated as the square root of variance by determining the variation between each data point relative to the mean.
The measure of dispersion that indicates how much scores in a sample vary around the mean of the sample is the standard deviation.
Therefore, option 2 is correct.
Answer:
Linear velocity of a rider in a capsule that is located at the perimeter of the wheel = 0.2355 m/s
Explanation:
Diameter = 135 m
Radius, r = 0.5 x 135 = 67.5 m
It revolves at a constant rate and takes 30 minutes
Period, T = 30 minutes= 1800 s
Linear velocity, v = radius x angular velocity
v = 67.5 x 3.98 x 10⁻³ = 0.2355 m/s
Linear velocity of a rider in a capsule that is located at the perimeter of the wheel = 0.2355 m/s
