NON-PARAMETRIC TEST SPEARMAN RANK ORDER Flashcards
Tests that do not require a normal distribution
non-parametric tests
They utilize nominal and ordinal data
non-parametric tests
categories
nominal data
ranks
ordinal data
skewness is positive or negative
not normal distribution
mean is < median it is negative
not normal distribution
mean is > median it is positive
not normal distribution

Nonparametric Tests
When the distribution is not normal use _ test
use Nonparametric Tests
When data is nominal or ordinal
use Nonparametric Tests
Sample size is smaller
use Nonparametric Tests
Spearman Rank Order Coefficient of
Correlation
non-parametric tests
Denoted by rs or ρs (rho)
Spearman Rank Order Coefficient of
Correlation
test of correlation that does not require the stringent assumption of normality like the Pearson r
Spearman Rank Order Coefficient of
Correlation
A nonparametric test used to find out if there is a significant
relationship between two variables, the IV and the DV.
Spearman Rank Order Coefficient of
Correlation
Data is nominal or ordinal.
Spearman Rank Order Coefficient of
Correlation
Report as 𝑟 𝑠 (df=n-2) = _____ (tabular value),p < .05 (level of significance)
Reporting Results of Spearman Rank Order Coefficient of
Correlation
If computed value is greater than tabular value, reject Ho.
Decision Results of Spearman Rank Order Coefficient of
Correlation
If computed value is _ than tabular value, reject Ho.
GREATER
If computed value is lower than tabular value, _ Ho.
ACCEPT HO
