Question description


Week 1 -
Discussion 2 – Measures of Variability and Central Tendency





Imagine you have collected information
on a health-related variable for 12 study participants.  For this
discussion, come up with 12 different data points pertaining to one continuous
variable and enter them into the first column in an Excel spreadsheet.  Examples
of potential variables include: age, temperature, body weight, height, systolic
blood pressure, number of minutes spent exercising/day, number of miles walked,
etc. You will then use the descriptive statistics option in Excel, which is
explained in Chapter 1 of your course text.  You should get an output
similar to Figure 1.2.  This output must contain the following values:
mean, standard error, median, mode, standard deviation, sample variance,
kurtosis, skewness, range, minimum, maximum, sum, count.  Begin your
discussion by identifying your variable, its unit of measurement (e.g. years
for age, pounds for body weight) and report your results for each of the
previously listed values.  Based on this output, which single value best
describes this set of data and why?  If you could pick three of these
values instead of only one, which three would you choose and why?  



Guided Response: Review several
of your classmates’ posts. Provide a substantive response to at least two of
your peers.  What does their data tell you about each of their fictitious
study populations?  Do you agree with their selections of the best value
based upon their data?
