26 Data Analysis in Business Research Step 1 Formulate a null and an alternate hypothesis: Ho: There is no significant difference in the proportion of wickets taken by countries A and B. Ha: There is a significant difference in the proportion of wickets taken by countries A and B. Percentage of Wickets Taken in the Last 20 Test Matches Country A Country B 5–6 7–8 9–10 11–12 13–14 15–16 17–18 1 3 1 2 2 1 3 4 3 2 2 2 1 1 19–20 7 5 Step 2 Find out the cdfs for each sample. Since it has been recommended to make use of as many intervals as are feasible to obtain a somewhat reliable ‘D’ value (Siegel, 1956:128), it has been arbitrarily proposed to cast the data (that is, the number of wickets taken) into 8 intervals as shown above.

Procedure 1. Formulate a null and an alternate hypothesis. The null hypothesis may be that there is no difference in the proportion of respondents in different categories of the variable while the alternative hypothesis may be that there is a difference in the number of respondents falling in different categories of the variable. 2. Cast the data in a tabular form. The data is simply the number of observations (Os) found in each category of variable. The number of categories will be denoted as ‘k’ while the sum of the frequencies in all the categories taken together will be denoted as ‘N’.

Use of an interval scale response is also possible as it can be converted into an ordinal scale. 3. Both 1- and 2-tailed tests can be effectively performed. While a 1-tailed K–S test is effective in testing the central tendency between 2 groups, a 2-tailed K–S test is effective in testing the significant difference between 2 groups with regard to central tendency, dispersion, or skewness. 4. The sample size of the 2 groups need not be equal. Procedure 1. Formulate a null and an alternate hypothesis.
