Boxplot ditafsirkan sebagai berikut:

  • The box itself contains the middle 50% of the data. Kotak itu sendiri berisi tengah 50% dari data. The upper edge (hinge) of the box indicates the 75th percentile of the data set, and the lower hinge indicates the 25th percentile. Tepi atas (engsel) dari kotak menunjukkan persentil ke-75 dari kumpulan data, dan engsel yang lebih rendah menunjukkan persentil 25. The range of the middle two quartiles is known as the inter-quartile range. Kisaran dua kuartil tengah dikenal sebagai antar-kuartil jangkauan.
  • The line in the box indicates the median value of the data. Baris dalam kotak menunjukkan nilai median dari data.
  • If the median line within the box is not equidistant from the hinges, then the data is skewed. Jika garis median dalam kotak tidak berjarak sama dari engsel, maka data miring.
  • The ends of the vertical lines or “whiskers” indicate the minimum and maximum data values, unless outliers are present in which case the whiskers extend to a maximum of 1.5 times the inter-quartile range. Ujung-ujung garis vertikal atau “kumis” menunjukkan minimum dan maksimum nilai data, kecuali jika terdapat outliers dalam hal ini ujung-ujung garis vertikal memperpanjang hingga maksimum 1,5 kali jarak antar-kuartil.

The points outside the ends of the whiskers are outliers or suspected outliers. Titik-titik di luar ujung kumis adalah outliers.
