statistikas termins, ko ikdienā jauc, apzināti un nepazināti, ar average (aritmētisko vidējo).

1,2, 3 =Median = 2 (vidējais skaitļu rindā)

1,2,3 = Average = 1,5 (skaitļu summas vidējais)

KLUDA piemeera: gan mediana gan videjais aritmetiskais dotaja skaitlu rindaa ir vienadi. Mediana reali ir videjais aritmetiskai skatlu ridas vidus veertiibaam. Izmanto in skewed skaitlu rindaas, jo dod preciizaaku vidusraadiitaaja veertiibu. Iespejams, kas mediciiniskaa izpeetee tas makes sense, jo videejais aritmeetiskais pacients ir stipri relatiiva lieta. Mediaaana uzraadiis tipiskaaku "videejo" pacientu.

Example 1 – Raw data (discrete variables)

Imagine that a top running athlete in a typical 200-metre training session runs in the following times:

26.1, 25.6, 25.7, 25.2 and 25.0 seconds.

How would you calculate his median time?

First, the values are put in ascending order: 25.0, 25.2, 25.6, 25.7, 26.1. Then, using the following formula, figure out which value is the middle value. Remember that n represents the number of values in the data set.

Median = (n + 1) ÷ 2th value
= (5 + 1) ÷ 2
= 6 ÷ 2
= 3

The third value in the data set will be the median. Since 25.6 is the third value, 25.6 seconds would be the median time.

= 25.6 seconds
