However, for most simple ordinal questions--either simple relationships or differences between groups with one independent variable, an equivalent statistical test is obtained by simply Ordinal scales with few categories (2,3, or possibly 4) and nominal measures are often classified as discrete and are analyzed using binomial class of statistical tests, whereas ordinal scales with many categories (5 or more), interval, and ratio, are usually analyzed with the normal theory class of statistical tests. In statistics, the terms "nominal" and "ordinal" refer to different types of categorizable data.
But when we apply an appropriate statistical test for comparison between means (in this case, the appropriate test is “t-test for unpaired data”), the result will be surprising. The only statistically significant difference is between the means of body temperature, exactly the opposite conclusion that the one expected by our general knowledge and experience.
