Instructions for Utilizing the Calculator

To use the Sturges' Rule Calculator effectively, follow these steps:

  • Fill in the Required Input Fields:
    1. Number of Data Points: Enter the total number of data points in your dataset. This field requires a numerical value.
    2. Bin Size: Specify the desired bin size for your histogram. This field also accepts numerical input.
    3. Data Type: Select the appropriate data type from the provided options: Continuous or Categorical. This selection determines the calculation method for the number of bins.

Note: All three input fields are mandatory and must be filled out to proceed with the calculation.

  • Optional Additional Options:
    1. Distribution: If applicable, select the distribution type of your data from the provided options: Normal, Uniform, or Exponential. This information can assist in further analysis.
    2. Height: Enter the height associated with your data, if relevant. Choose the appropriate unit of measurement from the dropdown menu.
  • Click the Calculate Button: Once you have entered the necessary information, click the Calculate button. The calculator will perform the calculations based on Sturges' Rule using the provided inputs.
  • Interpret the Results: After the calculation is complete, the results will appear in the table below the calculator. The output fields include:
    1. Number of Data Points: Displays the entered number of data points.
    2. Bin Size: Shows the specified bin size, including the unit of measurement.
    3. Data Type: Indicates the selected data type.
    4. Distribution: If provided, states the chosen distribution type; otherwise, displays N/A.
    5. Height: Presents the entered height value with the chosen unit of measurement.
    6. Number of Bins: Reveals the calculated optimal number of bins based on Sturges' Rule.

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.

  1. Enter the values in the respective input fields:
    • Number of Data Points: 250
    • Bin Size: 10
    • Data Type: Continuous
    • Distribution: Normal
    • Height: 175 cm
  2. Click the Calculate button.
  3. 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.
