Sturges' Rule Formula
The number of bins calculation in the Sturges' Rule Calculator follows this formula:
k = ceil(log2(n) + 1)
In the formula, k represents the number of bins, and n represents the number of data points in the dataset.
The formula determines the number of bins based on the logarithmic transformation of the data points. The result is then rounded up to the nearest whole number, ensuring a discrete and practical value for the number of bins.
Illustrative Example
Let's walk through an example to demonstrate the usage of the Sturges' Rule Calculator.
Suppose you have a dataset with 250 data points, and you want to create a histogram with a bin size of 10 units. The data type is continuous, and you have a normal distribution. Additionally, the associated height is 175 cm.
- Enter the values in the respective input fields:
- Number of Data Points: 250
- Bin Size: 10
- Data Type: Continuous
- Distribution: Normal
- Height: 175 cm
- Click the Calculate button.
- The calculator will perform the calculations, and the table below will update with the following results:
- Number of Data Points: 250
- Bin Size: 10 units
- Data Type: Continuous
- Distribution: Normal
- Height: 175 cm
- Number of Bins: 9
Based on Sturges' Rule, the calculator recommends using 9 bins for your histogram.
Illustrative Table Example
Here's an example table displaying multiple rows of data using the Sturges' Rule Calculator:
Number of Data Points | Bin Size | Data Type | Distribution | Height | Number of Bins |
---|---|---|---|---|---|
150 | 5 units | Continuous | Uniform | 180 cm | 8 |
500 | 1 unit | Categorical | N/A | N/A | 10 |
1000 | 20 units | Continuous | Exponential | 165 cm | 11 |
The table showcases different scenarios with varying data points, bin sizes, data types, distributions, heights, and the resulting number of bins.
