Consider the following frequency distribution.
Number of Minutes Frequency
0 to less than 5 6
5 to less than 10 9
8 to less than 13 14
13 to less than 18 2
Which rule for constructing a frequency distribution using grouped quantitative data has been violated?
A. Use mutually exclusive classes.
B. Use equal-size classes.
C. Avoid empty classes.
D. No rule has been violated.

Respuesta :

Answer:

A. Use mutually exclusive classes.

Step-by-step explanation:

From the given frequency distribution:

[tex]\left|\begin{array}{c|c}$Number of Minutes &$Frequency\\-------&------\\$0 to less than 5 &6\\$5 to less than 10& 9\\$8 to less than 13 &14\\$13 to less than 18 &2\end{array}\right|[/tex]

We can see that we have these class interval

  • 5 to less than 10
  • 8 to less than 13

The data in these two ranges will overlap and therefore violates the rule of mutual exclusivity.
