Chapter 11 Questions to be graded: 5. Were the experimental and control groups similar in their type of feeding? Provide a rationale for your answer. Answer: Yes the experimental and control groups are similar in their feeding type because 40.6% in the experimental group decided to breast-feed‚ and 41.7% in the control group decided to breast-feed‚ that’s only 1.1% difference. 53.1% of the experimental group bottle-fed while 50.0% of the control group bottle-fed‚ a small 3.1% difference.

the September 11 terrorist attacks‚ the measures of central tendency and the measures of dispersion could be used. The measures of central tendency are simply a statistic used to present data in the form of averages. The most common measures of central tendency are the arithmetic mean‚ the median and the mode. The measures of dispersion tell you how widely spread out or scattered these values are. The range and standard deviation are two examples. Measure of Central Tendency Themes # of

EXERCISE 11 1. What demographic variables were measures at least at the interval level of measurement? a. The number of hours worked per week and the length of labor (hrs) 2. What statistics were used to describe the length of labor in this study? Were these appropriate? a. Length of labor for both the control and experimental groups were described with mean and standard deviations. Yes‚ these were appropriate measures of statistics. 3. What other statistics could have been used to describe the

Self-care and efficacy – 14.02 baseline to 12.24 post. Depression – 10.88 baseline to 10.45 post). A smaller change in SD indicates that the data tends to stay close to the mean. 6.
