Calcolatore dei quartili

Calcola Q1, la mediana e Q3 di un insieme di dati.

Introduzione

Quartiles Calculator — Compute Q1, median, and Q3 of a dataset. Enter Dataset (comma-separated) to get an instant, accurate result.

Formula

Q1, Q2 (median), and Q3 are the 25th, 50th, and 75th percentiles of the sorted data, found by linear interpolation.

Passo dopo passo

  1. Enter the Dataset (comma-separated).
  2. Click Calculate to see your result instantly.

Esempio pratico

Example: With Dataset (comma-separated) = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, the Quartiles Calculator gives Q1: 3.25, Q2 Median: 5.5, Q3: 7.75.

Domande Frequenti

What do quartiles tell you?
They split the data into four equal-sized groups, showing how values are distributed across the low, middle, and high ranges.
Is Q2 the same as the median?
Yes, the second quartile is always equal to the median.
What inputs does the Quartiles Calculator need?
You'll need to provide: Dataset (comma-separated). All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Quartiles Calculator?
The Quartiles Calculator applies the formula exactly as calculated — Q1, Q2 (median), and Q3 are the 25th, 50th, and 75th percentiles of the sorted data, found by linear interpolation. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Quartiles Calculator free to use?
Yes, the Quartiles Calculator is completely free, requires no signup, and runs instantly in your browser.

Informazioni su Calcolatore dei quartili

The Quartiles Calculator uses a real, verifiable formula — Q1, Q2 (median), and Q3 are the 25th, 50th, and 75th percentiles of the sorted data, found by linear interpolation. — so results are accurate every time, not an approximation.
