Frequency Distribution

Frequency Distribution

Method of presenting categories or scores with their corresponding frequencies of occurrence.

Frequency

The number of times a specific value or range of values occurs in a dataset.

Categorical Variables

Variables that represent categories or groups in a dataset.

Grouping Scores

Organizing individual scores into intervals to facilitate data analysis.

Class Interval

A range of values used to group and categorize data in a frequency distribution.

Central Tendency

A central value that represents the middle or center of a distribution.

Range

The difference between the highest and lowest values in a dataset.

Interval Width

The size of the range covered by each class interval in a frequency distribution.

Real Limits

The actual numerical boundaries of a class interval.

Tally

Marking or counting occurrences of values falling within specific intervals in a frequency distribution.

Constructing Frequency Distribution

The process of creating a table or graph to display the frequency of values in a dataset.

Data Set

A collection of values or observations that are analyzed as a whole.

Visualization

Presenting data in a visual form to aid understanding and interpretation.

Accuracy

The degree of correctness or precision in the measurement or representation of data.

Distribution

The way in which values or observations are spread out in a dataset.

Summing Frequencies

Adding up the total number of occurrences for each class interval in a frequency distribution.

Exercise

A set of data or values used for practice or analysis in statistical studies.

Statistics

The branch of mathematics that deals with the collection, analysis, interpretation, and presentation of data.

Data Analysis

The process of examining, cleansing, transforming, and modeling data to uncover useful information.

Interpretation
