A. Mid oint
B. Quartiles
C. Class
D. Frequencies
Answer is = D
You’re right! Out of the given options, the number of scores lying in a class interval is referred to as:
D. Frequencies
Here’s why the other options are not used to represent the number of scores in a class interval:
- A. Midpoint: This refers to the central value of a class interval, calculated by averaging the lower and upper limits. It doesn’t tell you how many scores fall within that interval.
- B. Quartiles: These are specific points in a data set that divide it into four equal quarters. They don’t directly represent the number of scores within a particular class interval.
- C. Class: This refers to the category or grouping used in a frequency distribution table. It doesn’t specify the number of scores within that class.
Frequencies, on the other hand, specifically refer to the number of observations or scores that fall within a particular class interval in a frequency distribution table. They are essential for understanding how data is distributed across different intervals.
Here are some additional points to consider:
- Frequencies can be absolute (the actual number of scores) or relative (the percentage of scores within a class interval).
- Frequency tables and histograms are common ways to visually represent frequencies associated with different class intervals.
