Number of Classes given Class Width Solution

STEP 0: Pre-Calculation Summary

Formula Used

Number of Classes = (Largest Item in Data-Smallest Item in Data)/Class Width of Data
N_Class = (Max-Min)/w_Class
This formula uses 4 Variables

Variables Used

Number of Classes - Number of Classes is the count of intervals or groups into which the data is divided in a frequency distribution.
Largest Item in Data - Largest Item in Data is the highest value in the dataset, indicating the upper extreme of the observed values.
Smallest Item in Data - Smallest Item in Data is the lowest value in the dataset, indicating the lower extreme of the observed values.
Class Width of Data - Class Width of Data is the difference between the upper and lower boundaries of a class or interval in a frequency distribution.

STEP 1: Convert Input(s) to Base Unit

Largest Item in Data: 85 --> No Conversion Required
Smallest Item in Data: 5 --> No Conversion Required
Class Width of Data: 4 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

N_Class = (Max-Min)/w_Class --> (85-5)/4

Evaluating ... ...

N_Class = 20

STEP 3: Convert Result to Output's Unit

20 --> No Conversion Required

FINAL ANSWER

20 <-- Number of Classes

What is the Classification of data in Statistics?

For performing statistical analysis, various kinds of data are gathered by the investigator or analyst. The information gathered is usually in raw form which is difficult to analyze. To make the analysis meaningful and easy, the raw data is converted or classified into different categories based on their characteristics. This grouping of data into different categories or classes with similar or homogeneous characteristics is known as the Classification of Data. Each division or class of the gathered data is known as a Class. The different basis of classification of statistical information are Geographical, Chronological, Qualitative (Simple and Manifold), and Quantitative or Numerical.
For example, if an investigator wants to determine the poverty level of a state, he/she can do so by gathering the information of people of that state and then classifying them on the basis of their income, education, etc.

How to Calculate Number of Classes given Class Width?

Number of Classes given Class Width calculator uses Number of Classes = (Largest Item in Data-Smallest Item in Data)/Class Width of Data to calculate the Number of Classes, Number of Classes given Class Width formula is defined as the count of intervals or groups into which the data is divided in a frequency distribution, and calculated using the class width of the data. Number of Classes is denoted by N_Class symbol.
