The answer is c because if the survey says 3 out of 8 have one you divide 3/8 and multiply it by 192.
Answer:
The answer is a: Number of items in several classes.
Step-by-step explanation:
Frequency distributions are tables that represent the number of times a specific data, number object etc appears in a sample. So for example if we have this data
2,2,4,4,6,6,6,8,8,10
The frequency distributions is
Number frequency
2 2
4 2
6 3
8 2
10 1
The other options are identical (c and are the same as percentages can be expressed as fractions. Relative percentages or fractions are tables that express the weight that each category has in the entire data. An example for our data would be: (10 are the total number of obs)
Number Fraction/%
2 2/10 or 20%
4 2/10 or 20%
6 3/10 or 30%
8 2/10 or 20%
10 1/10 or 10%
The interquartile range<span> (</span>IQR<span>) is a measure of variability, based on dividing a </span>data set<span>into quartiles. Quartiles divide a rank-ordered </span>data set<span> into four equal parts. The values that divide each part are called the first, second, and third quartiles; and they are denoted by Q1, Q2, and Q3, respectively.</span>
