How do you determine the class limits for a frequency table?

Back

Class limits are determined by dividing the range of data into equal intervals. The lower limit of the first class is the smallest value, and the upper limit is the smallest value of the next class.

FLASHCARD QUESTION

Front

What is the purpose of using classes in a frequency table?

Back

Classes are used to group data into intervals to simplify the analysis and visualization of large datasets.

5.

FLASHCARD QUESTION

Front

How do you calculate the number of classes for a frequency table?

Back

The number of classes can be determined using Sturges' formula: k = 1 + 3.322 log(n), where k is the number of classes and n is the number of data points.

FLASHCARD QUESTION

Front

What is the difference between inclusive and exclusive class limits?

Back

Inclusive class limits include the endpoints (e.g., 0-10 includes both 0 and 10), while exclusive class limits do not include the upper endpoint (e.g., 0-10 excludes 10).

FLASHCARD QUESTION

Front

How do you find the frequency of a class in a frequency table?

Back

The frequency of a class is found by counting the number of data points that fall within the class limits.
