Statistics Project Example In this case, a description of the length of labor could have been initiated whereby the length of labor of one works would be considered as a random variable. A probability distribution that provides a description to such a random variable would them be initiated. 4. The distributions of scores for the experimental and control groups were not similar for the length of labor because the two means were different. The mean of the experimental group was 14.63 while that of the control group was 12.79, portraying a mean difference of 1.84 (Troy & Dalgas-Pelish, 2003). 5. The experimental and control groups were slightly in their type of feeding since in all types of feeding such as bottle feeding, breast feeding, as well as the combination of the two modes of feeding depicted a difference in their mode, as a measure of central tendency (Mann, 1995). Breast-feeding was found to have a mode of 40.6% for the experiment group against 41.7% for the control group, while bottle-feeding had a mode of 53.1% against 50.0% for the experimental group and control group respectively. On the other hand, the combination of both the breast and bottle-feeding showed a mode of 6.3 and 5.6 for the experimental group and the control group respectively (Troy & Dalgas-Pelish, 2003). 6. The marital status mode for the subjects in the experimental and control groups included 78.1% for the married subject in the experimental group, against 86.1% for the control group. The mode also included 3.1% for the separated/divorced subjects in the experimental group against 2.1% in the control group, and 18.8% for the single subjects in the experimental group, against 8.3 in the control group (Troy & Dalgas-Pelish, 2003). The frequencies for these three subject categories for the experimental groups against the control groups were 0.781 vs. 0.861, 0.031 vs. 0.021, and 0.188 vs. 0.083 for the married, separated/divorced, and single subjects respectively. 7. The median for the education data cannot be
