Introduction
Understanding and interpreting data is a vital component to a learner’s research as it reflects the study results. Properly analyzing the data is also crucial as this portrays the outcomes and delivers research findings which is the purpose of completing the study initially. Once data is extracted and analyzed, further development of the topic is discussed and shared allowing for a deeper sense of knowledge of the included variable, perceptions, and anything discovered throughout the study. Astroth and Chung (2018) discussed the importance of reviewing quantitative research studies highlighting the importance of ensuring the results are presenting and interpreted correctly. This article is geared towards nurses as they utilize evidence-based practices throughout many health care settings therefore properly analyzing data and accurately reporting results is critical in the potential care provided. For the purpose of this paper, the learner completed the assigned tasks of Module 2 Problem set which is provided below.

2. (a) For which of these variables is it appropriate to use the median? (b) What conclusions can you draw about the distributions of these variables?
a. The variables for which it is most appropriate to use the median are high school education (paeduc) and Job or Housework (satjob) as these measurements are best for this category.
b. The conclusions that can be drawn include that with more education, the higher propensity of having full time employment. More than half reported being satisfied with their employment and more than half did not attend college.
3. (a)What percent of respondents have a bachelor’s degree, or higher? (b)What percent of respondents are working?
a. 14.7% of respondents have a bachelor’s degree or higher
b. 60% of respondents are working either full time or part time
4. How might you combine some of the categories of wrkstat to ensure that there are a sufficient number of respondents in each category?
a. Completing a summary analysis could lend support in determining grouping availability however some of categories that could ensure a sufficient amount of respondents could be employed, retired, and keeping house as they represent cross-categories with high percentages to fulfill the gap.

2. (a) What is the value of value of alcohol that splits the distribution in half? (b) Is the median the same as the mean? (c) Which value is lower? (d) What does that tell you about the shape of the distribution of alcohol?
a. 4.7 splits the distribution in half
b. The mean and median are not the same as the mean is 4.5771 and the median is 4.7
c. The mean of 4.5771 is lower than the median of 4.7
d. The data is skewed negatively which is indicated by the longer tail
3. (a) Does the histogram verify your description of the distribution of alcohol? (b) How does it differ from a normal distribution?
a. Yes, as it does support being it shows a negative distribution on the left versus a positive distribution on the right which presents alignment
b. Normal distribution is centered and symmetrical which is not apparent as it is skewed left presenting a negative distribution.
4. Run Descriptives to obtain default statistics for price and calories. (a) On which variable is there more dispersion? (b) Is it even realistic to compare these two variables since they are on…
