Eight common non-parameter tests in spss iii: Travel Test

I. Definition

Definition: the random test of the single sample variable value is to check whether the value of a variable is random, also known as the Run process ).

The random test of the single sample variable value was proposed by Wald. Its zero hypothesis is H0: The variable value of a certain population variable is random.

The random test of a single sample variable value is implemented by the Run number. A run is the number of consecutive variable values in a sample sequence.

In the random test of variable values in a single sample of SPSS, SPSS constructs the Z-statistic using a run, and gives the corresponding accompanied probability value based on the normal distribution table. If the accompanied probability is less than or equal to the user's significance level α, we should reject the null hypothesis H0, and think that the appearance of the sample value is not random. If the accompanied probability value is greater than the significance level, then, the null hypothesis H0 cannot be rejected, and the appearance of variable values is random.

 

Ii. Instances

A resident of a village is listed along a river. During the investigation, the resident of the village is marked as "1" and the resident of non-resident is marked as "0 ", A total of 35 households have the following values.

 

Household	Incidence	Household	Incidence	Household	Incidence
1	1	13	1	25	1
2	0	14	1	26	1
3	1	15	1	27	0
4	1	16	1	28	1
5	1	17	0	29	0
6	1	18	0	30	0
7	0	19	1	31	1
8	0	20	1	32	0
9	0	21	0	33	0
10	0	22	0	34	0
11	1	23	1	35	0
12	1	24	1
