Explanation / Answer

The sample size refers to take two data (category or classes) to establish a comparison, for this is necessary to obtain a weight measure (two measures), then we must obtain the mean for each pair of data. If we need to calculate probability, it will be P = 1/N (N = population size) See the example below:

For N = 10 size

Weight: measure values
Sample: two measures (data)

Probability: 1/N (One refers to each combination of samples)

Sample

Weight

(Mean of two samples)

Probability

F, G

12, 14

= 12 + 14/ 2 = 13

P = 1/10

H, I

15, 17

= 15 + 17/ 2 = 16

P = 1/10

J, K

20, 24

= 20 + 24/ 2 = 22

P = 1/10
