T-test and Correlation - Statistics Project ExampleThis paper will analyze variation in the percentage habitude of prepositions in writing between inherent and non native speaker of face in their texts. For this, 10 texts written by a native speaker of English and another 10 texts written by a non-native speaker of English (Arab writer) in the usage (percentage) of prepositions were collected (table 1).The research hypothesis is Is on that point a going in the use of prepositions in writing between native and non native speaker of English?The null and alternate hypotheses areH0native = non-nativeH1native non-nativeThe selected level of significance, is 0.05.The test selected is two-tailed t-test for independent samples (Independent Samples Test) because alternate hypothesis involves not equal to sign ().The average percentage use of prepositions in writing for non-native speaker of English in their text is 38.50 (SD = 6.35). The average percentage use of prepositions in writi ng for native speaker of English in their text is 38.30 (SD = 4.64). From figure 1, it appears that there is no difference in the use of prepositions in writing between native and non-native speaker of English.The Levenes test for equality of section is not significant, F(1, 18) = 1.90, p = .19 (.05). Therefore, equal variance can be assumed for t-test.The null hypothesis H0 is retained. Therefore, there is no difference in the use of prepositions in writing between native and non native speaker of English, t(18) = 0.08, p = .94 (.05).Both data set (data set 1 and data set 2) shows no correlation, r(8) = .06, p = .87 (.05).In conclusion, data suggest that there is no difference in the usage of prepositions in writing between native and non native speaker of English.
