Global Happiness: Everything Up to the Paired-Samples t Test
What statistical analysis could be used to determine whether this region has a statistically significantly different
In which of the following four categories does the situation fall?
a. only scale nominals
b. nominal independent variables, scale dependent variables
c. only nominal variables
d. any ordinal variables (that cannot be treated as nominal)
The region being studied is a nominal independent variable, as it is a categorical variable with a finite number of distinct values.
A z-test could be used to determine whether the mean of the dependent variable in the region is significantly different from the global population mean. The z-test is a statistical test used to compare the mean of a sample to a known population mean, when the population standard deviation is known or the sample size is large (n >= 30).
