A spinner has three unequal sections.
Red = 10
Yellow = 14
Blue = 6
We are asked to find the experimental probability of landing on yellow.
Recall that the experimental probability is given by
In this case, the number of desired outcomes are
Yellow = 14
The total number of possible outcomes is
Total sections = 30
Therefore, the experimental probability of landing on yellow is 7/15
Answer:
A. The coefficient of variation is best used when comparing two data sets that use the same units of measure.
Step-by-step explanation:
The coefficient of variation (CV), is simply the standard deviation (itself a measure of variance or variation) relative to the mean of a distribution.
The coefficient of variation expresses a random variable’s variability in percentage terms. Therefore it is possible, through the coefficient of variation, to compare the variability of data across different samples, especially if the random variables are recorded in different units of measurement (such as cm, kg and minutes).
A coefficient of variation is always interpreted as a percentage. <u>Mathematical representation is:</u>
The coefficient of variation is best used when comparing two data sets that use the same units of measure.
Hence, the option (A) is the correct option.
