Probability
Definition: Statistics
Statistics is the area of study dealing with the collection, presentation, and analysis of data as well as drawing meaningful conclusions from the data.
Definition: Data
A collection of given facts or figures, usually expressed in numerical form.
Definition: Frequency
Frequency:
The number of times a particular observation occurs.
Frequency Distribution:
A tabular arrangement of data showing the frequency of each observation or class.
Definition: Class Interval
Each group into which raw data is divided is called a class interval.
Definition: Class Limits
The two values that bound a class interval.
-
Lower limit: Smallest value of the class
-
Upper limit: Largest value of the class
Definition: Inclusive and Exclusive Forms
-
Inclusive form: Both lower and upper limits are included in the class.
(Example: 1–10, 11–20) -
Exclusive form: Lower limit is included, but upper limit is excluded.
(Example: 0–10, 10–20)
Definition: Range
The difference between the highest and lowest observations.
Range = Highest value − Lowest value
Formula: Adjustment Factor
\[\text{Adjustment Factor}=\frac{1}{2}\text{(Lower limit of next class - Upper limit of previous class)}\]
Formula: Frequency Density
\[\text{Frequency density}=\frac{\mathrm{Frequency}}{\text{Class width}}\]
