Advance Statistics



Currently,I am working at the NCLEX Memorial Hospital under the InfectiousDiseases Unit. Over the past days, there has been an increase innumber of patients that are admitted with a given infectious disease.From the data set that I gathered, I believe that ages of thepatients are critical in determining the method used to treat thepatients. This paper focuses on the statistical analysis of the datawith close look at the ages of the patients. The analysis will bedependent on the data that is on the spreadsheet. This data set ismade of 60 patients who have infectious disease and are of ageranging from 35 years to 76 years of age for the NCLEX MemorialHospital.


Thevariables under this study include the age of patients and infectionstatus. Age of patient is quantitative while the infectious status isqualitative in nature. The age is discrete in number as we have awhole number.

Measuresof Center Tendency and Measures of Variation

Measuresof central tendency describe a set of data through identification ofcentral position in a given data set. They are known to be summarystatistics. The main types of measures of central tendency includethe mean, median and the mode (Mueller, 1977). They are important inserving comparisons as they allow one to compare one piece of data tothe entire data set. They often form basis for further statisticalanalysis like measures of dispersion.

Measuresof Variation

Measuresof variation express the degree of variation or spread in a randomvariable. They describe the distribution of data (Mueller, 1977).Some of them include standard deviation, quartiles, variance, range,and outliers. Helps in measuring the variation of a set of data inregards to the amount

Calculationof Measures of Central Tendency and Measures of Variation



Theaverage age of the persons in this study is at 61.816667





Themost frequent occurring age in the group of the study population is69



Thisgives the mid-point of the range.


Theage range of the population is 41 and is the difference of the eldestfrom the youngest in the study




Thevalue gives the squared differences from the average age of thepopulation



Thismeans that the mean age of the population is spread by 8.849654733 onlower or upper side.


Thispaper has classified the two variables in this study, age andinfection status. The classification has either been qualitative orquantitative. Also, the variables have been found to be discrete innature. Further, the paper explained the meaning of measures ofcentral tendency and measures of variation. Their respectivesignificances are also highlighted. Calculation of each of thestatistics are also provided and their interpretations. This paperclearly explains the data set used at NCLEX Memorial Hospital.
