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
NClass = (Max-Min)/wClass
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
NClass = (Max-Min)/wClass --> (85-5)/4
Evaluating ... ...
NClass = 20
STEP 3: Convert Result to Output's Unit
20 --> No Conversion Required
FINAL ANSWER
20 <-- Number of Classes

18 Basic Formulas in Statistics Calculators

P Value of Sample
Go P Value of Sample = (Sample Proportion-Assumed Population Proportion)/sqrt((Assumed Population Proportion*(1-Assumed Population Proportion))/Sample Size)
Sample Size given P Value
Go Sample Size = ((P Value of Sample^2)*Assumed Population Proportion*(1-Assumed Population Proportion))/((Sample Proportion-Assumed Population Proportion)^2)
t Statistic of Normal Distribution
Go t Statistic of Normal Distribution = (Sample Mean-Population Mean)/(Sample Standard Deviation/sqrt(Sample Size))
t Statistic
Go t Statistic = (Observed Mean of Sample-Theoretical Mean of Sample)/(Sample Standard Deviation/sqrt(Sample Size))
Chi Square Statistic
Go Chi Square Statistic = ((Sample Size-1)*Sample Standard Deviation^2)/(Population Standard Deviation^2)
Number of Classes given Class Width
Go Number of Classes = (Largest Item in Data-Smallest Item in Data)/Class Width of Data
Class Width of Data
Go Class Width of Data = (Largest Item in Data-Smallest Item in Data)/Number of Classes
Expectation of Difference of Random Variables
Go Expectation of Difference of Random Variables = Expectation of Random Variable X-Expectation of Random Variable Y
Chi Square Statistic given Sample and Population Variances
Go Chi Square Statistic = ((Sample Size-1)*Sample Variance)/Population Variance
Expectation of Sum of Random Variables
Go Expectation of Sum of Random Variables = Expectation of Random Variable X+Expectation of Random Variable Y
Number of Individual Values given Residual Standard Error
Go Number of Individual Values = (Residual Sum of Squares/(Residual Standard Error of Data^2))+1
F Value of Two Samples given Sample Standard Deviations
Go F Value of Two Samples = (Standard Deviation of Sample X/Standard Deviation of Sample Y)^2
Mid Range of Data
Go Mid Range of Data = (Maximum Value of Data+Minimum Value of Data)/2
F Value of Two Samples
Go F Value of Two Samples = Variance of Sample X/Variance of Sample Y
Smallest Item in Data given Range
Go Smallest Item in Data = Largest Item in Data-Range of Data
Largest Item in Data given Range
Go Largest Item in Data = Range of Data+Smallest Item in Data
Range of Data
Go Range of Data = Largest Item in Data-Smallest Item in Data
Relative Frequency
Go Relative Frequency = Absolute Frequency/Total Frequency

Number of Classes given Class Width Formula

Number of Classes = (Largest Item in Data-Smallest Item in Data)/Class Width of Data
NClass = (Max-Min)/wClass

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 NClass symbol.
