We create a frequency distribution for interval data by counting the number of observations that fall into each of a series of intervals, called?
Homework Answers
answer is:- classes
Explanation:-We create a frequency distribution for interval data by counting the number of observations that fall into each of a series of intervals called classes, that cover the complete range of observations.

Which of the following is NOT a rule for constructing a simple frequency distribution? Question 1 options: The number of class intervals should equal the number of observations measured. Each interval is equidistant. No overlapping class intervals are allowed. Values are rounded to the same degree of accuracy measured in the original data.

Outliers: We know many types of data fall into a normal distribution with most of the observations falling toward the middle. However, sometimes data are outliers or data that are very different—larger or smaller—from the rest of the members of the sample. Think of an example in the real world of an outlier and discuss its effect.
