2-3 Journal: Module Two (Example)

Document Preview:

Name Course Tutor Date Journal: Module Two The data considered by the project is the data for the monthly weather data from January 1930 to December 1958. The primary purpose of the analysis is to test the normality of two particular variables via two main statistical tests including the bell-shaped feature and checking for the presence of outliers. Bell shaped is the mathematical concept commonly known as Gaussian distribution created when the line is plotted using data points for a variable to test whether the variable meets (points) have gaps to the next one. The graph shows that there are gaps between the last three bins. Conclusively the analysis indicates that DP05 is statistically likely to be normally distributed because the histogram shows a bell-shaped evidence and absence of outliers. On the other hand EMXP histogram suggests that there is no bell-shaped characteristics and presence of outliers. Outliers hurt the calculation of central tendency measures such as the mean. Therefore the analysis indicate that DP05 is normally distributed and EXMP is not normally distributed [...]

Order Description:

Using the Journal Dataset, consider the variable DP05 (days with precipitation that is more than 05 tenths of an inch). This is the number of days in each month that had 0.5 inches or more of precipitation. For example, a value of 3 in DP05 means that during three days of that month, it rained or snowed (equivalent) more than half an inch. Draw a histogram of DP05. Does DP05 have an approximately normal distribution? Does it have an obvious skew (left or right) and any obvious outliers? If an analysis requires that DP05 have a normal distribution, do you think that your results will be valid? Now consider the variable EMXP (extreme maximum precipitation). That is the extreme precipitation in each month, in tenths of a millimeter. For example, a value of 300 in EMXP means that it rained 30 millimeters on the rainiest day of that month. Draw a histogram of EMXP. Does EMXP have an approximately normal distribution? Does it have an obvious skew (left or right) and any obvious outliers? If an analysis requires that EMXP have a normal distribution, do you think that your results will be valid? For additional details, please refer to the Module Two Journal Aid Transcript document, Journal Rubric document, and Journal Data Set document in the Assignment Guidelines and Rubrics section of the course.
