Question

20 students were asked about their favorite college class the results are listed below let 8 equals astronomy be equal biology C equal chemistry M equal mathematic and E equal English

Answer 1

The Solution.

The frequency table of the given data is as below:

The data in the table above is QUANTITATIVE.

The relative frequency of the data above is calculated thus:

The relative frequency of Astronomy (A) is

$\frac{n\text{umber of A}}{\text{total frequency}}=\frac{6}{20}=\frac{3}{10}=0.3$

The relative frequency of Biology (B) is

$\frac{n\text{umber of B}}{\text{total frequency}}=\frac{2}{20}=\frac{1}{10}=0.1$

The relative frequency of Chemistry (C) is

$\frac{n\text{umber of C}}{\text{total frequency}}=\frac{4}{20}=\frac{1}{5}=0.2$

The relative frequency of Mathematics (M) is

$\frac{n\text{umber of M}}{\text{total frequency}}=\frac{3}{20}=0.15$

The relative frequency of English is

$\frac{n\text{umber of M}}{\text{total frequency}}=\frac{5}{20}=\frac{1}{4}=0.25$
