In this paper, we examined a test statistic for testing ordered alternative hypothesis under unequal group variances. The proposed modified t – test statistic obtained by replacing the pooled sample variance with the corresponding harmonic mean of variances in other to avoid the Behren – Fisher’s problem. The distribution of the sample of harmonic mean of variances which is known to be generalized Beta is approximated by the chi – square using a condition that is easily satisfied. The result shows that the modified t – test statistic is found to be appropriate for the data set obtained from Kwara Agricultural Development Project (KWADP) where the crop yields of the treatment means were known to be in a particular order because of ecological conditions.
Alternative Hypothesis – Obesity is a growth disorder, just like any other growth disorder, and fat accumulation is determined not by the balance of calories consumed and expended but by the effect of specific nutrients on the hormonal regulation of fat metabolism.

PROC FREQ computes onesided and twosided pvalues for the JonckheereTerpstra test. When the standardized test statistic is greater than its null hypothesis expected value of zero, PROC FREQ displays the rightsided pvalue, which is the probability of a larger value of the statistic occurring under the null hypothesis. A small rightsided pvalue supports the alternative hypothesis of increasing order from row 1 to row . When the standardized test statistic is less than or equal to zero, PROC FREQ displays the leftsided pvalue. A small leftsided pvalue supports the alternative of decreasing order from row 1 to row .
The JT option in the TABLES statement provides the JonckheereTerpstra test, which is a nonparametric test for ordered differences among classes. It tests the null hypothesis that the distribution of the response variable does not differ among classes. It is designed to detect alternatives of ordered class differences, which can be expressed as (or ), with at least one of the inequalities being strict, where denotes the effect of class . For such ordered alternatives, the JonckheereTerpstra test can be preferable to tests of more general class difference alternatives, such as the Kruskal–Wallis test (produced by the WILCOXON option in the NPAR1WAY procedure). See Pirie (1983) and Hollander and Wolfe (1999) for more information about the JonckheereTerpstra test.
Processing Survey Data with Ordered Alternative …
This module presents hypothesis testing techniques for situations with small sample sizes and outcomes that are ordinal, ranked or continuous and cannot be assumed to be normally distributed. Nonparametric tests are based on ranks which are assigned to the ordered data. The tests involve the same five steps as parametric tests, specifying the null and alternative or research hypothesis, selecting and computing an appropriate test statistic, setting up a decision rule and drawing a conclusion. The tests are summarized below.
