Identify the correct chronology of the following :
I. Fisher’s test of significance of differences between means of three or more samples.
II. Kendal’s partial rank correlation.
III. Gossest’s T test of significance between means of two samples. IV. χ² test of goodness of fit of the curve and randomness of the sample values.
Answer and explanation
Correct answer C
Arranging the four statistical tests in chronological order of their historical development and publication: (IV) Karl Pearson's χ² (Chi-square) test of goodness of fit was published in 1900; (III) William Sealy Gosset's ('Student's') t-test of significance between two sample means was published in 1908; (I) R.A. Fisher's F-test / analysis of variance (ANOVA) for differences between means of three or more samples was developed in 1918–1925; and (II) Maurice Kendall's rank correlation (1938) and partial rank correlation (1942) came last. Therefore, the chronological sequence is IV, III, I, II .
