45 The ‗Paired Samples Correlations‘ table shows the Pearson correlation coefficient
and its significance value. This test is conducted to show if the results found are consistent. The result indicates r= 0.892, p = 0.000, which is found to be
significant as p 0.05. The students are therefore said to have behaved consistently as their scores in the pretest are significantly correlated with their
scores in the posttest. The next table that SPSS
®
produces is the ‗Paired Samples Test‘ table, which informs us if there is a significant difference between the means or not. The
pvalue in the ‗Paired Samples Test‘ table is for a two-tailed hypothesis shown in
the column ‗Sig. 2-tailed‘. As the hypothesis in this research is one-tailed, the p value should be divided by two, which gives us the same figure, i.e. 0.000. The
conventional way of reporting the findings is to state the test statistic t, degrees of freedom df, and probability value p. The results are reported as follows:
The t table value for p = 0.05, one-tailed hypothesis, and df = 29 is 1.699. As the calculated t value 9.672 is larger than the t table value, and p 0.05, it is
concluded that there is significant increase of students‘ reading comprehension achievement in the posttest after the application of TPS technique the minus sign
in the calculated t value is caused simply by the fact that the mean of the first sample pretest is smaller than that of the second sample posttest.
