About the Central Tendency Calculator

The Central Tendency Calculator computes the mean, median, and mode of a dataset, providing insights into its central value. Ideal for statistical analysis, data science, and educational purposes.

Enter numbers separated by commas using the buttons or keyboard.
Press Calculate to view dataset size, mean, median, and mode.
Use Clear to empty the input or Backspace (⌫) to delete the last character.

How to Use the Central Tendency Calculator

Follow these steps:

Enter Data: Input numbers separated by commas (e.g., 1, 2, 3, 4).
Enter Values: Use number buttons (0-9, 00, .), Comma (,), or keyboard.
Correct Input: Use Backspace (⌫) to delete the last character or clear the field.
Calculate: Press the “Calculate” button to display results.
Clear or Reset: Use “Clear” to empty the input.

Notes:

Ensure inputs are valid numbers (decimals supported; negative values allowed).
Empty inputs or invalid formats will display an error.
Keyboard support: Numbers, decimal point, comma, Enter for calculation, Backspace to delete.

Central Tendency Explained

Measures of central tendency describe the center of a dataset:

Mean (Average):
\( \text{Mean} = \frac{\sum x_i}{n} \)
Sum of all values (\( x_i \)) divided by the number of values (\( n \)).

Median:
The middle value when data is sorted. For even \( n \), average the two middle values.

Mode:
The value(s) that appear most frequently. A dataset may have multiple modes.

Assumptions:

Results are rounded to two decimal places for mean and median.
Mode lists all values with the highest frequency.
Inputs must be valid numbers separated by commas.

Example Calculation

Calculate central tendency for the dataset: 1, 2, 2, 3, 4

Enter Data: Input “1, 2, 2, 3, 4”.
Calculate: Press “Calculate”.
– Size: 5 values
– Mean: \( \frac{1 + 2 + 2 + 3 + 4}{5} = \frac{12}{5} = 2.40 \)
– Median: Sorted: 1, 2, 2, 3, 4; Middle value = 2
– Mode: 2 (appears twice, most frequent)
Result: Size: 5, Mean: 2.40, Median: 2.00, Mode: 2
