Since length of labor provides interval/ratio data so Range can also be used to analyze the data. 4. The distributions of scores in control and experimental groups for the length of labor are not similar neither it is significantly different for the groups. The mean (M) for the length of labor indicates (12.79 control group and 14.63 experimental group), 1.84 variation. The standard deviation (SD) for the length of labor indicates (7.78 experimental group and 7.2 control group), a variation of 0.58.

Which of the following is a characteristic of the F distribution? a) Normally distributed b) Negatively skewed c) Equal to the t-distribution d) Positively skewed Complete Answers here QNT 561 3. For a chi-square test involving a contingency table, suppose the null hypothesis is rejected.

Conclusion: There is sufficient evidence to indicate that the mean times required to complete a certain task differ for at least two of the three levels of training. Which pairs of means differ? The Bonferroni Test is done for all possible pairs of means.
