CASE S : F ATUDY ACTORIAL NALYSIS OF V TARIANCE EMPLATE
Instructions: To successfully complete this case study, all of the following instructions must be
adhered to. Only paste tables/figures that contain pertinent information. Only paste tables/
figures where you are instructed to do so. HIGHLIGHT (in yellow) only relevant the data from
tables; as well as your response to each question. In the write-up section, all information must be
provided in paragraph format. When statistical values are discussed, the numerical value must be
given and a reference must be made to the table(s)/figure(s) where the value(s) can be found. An
example of this is “heart rate was statistically greater during running versus cycling (189 vs. 143
bpm) as indicated in Table 1.
I. Factorial Analysis of Variance
Research question: “is there a statistical difference for skin temperature across time
while taking into account the “factor” “environment” (hot versus cold)?”
Assumptions Testing
1. Data level of measurement- what is the level of measurement for the data used in this
case study?
The environment variable was nominal, and the time was ratio.
2. Would the amount of skewness and kurtosis in these affect the analysis? How do you
know? Give numerical values to support your conclusion.
Time 0 in the hot environment was not skewed or kurtotic with vales of 1.89 and 1.52
respectfully which are between 1.96 and -1.96. Time 0 in the cold environment was
skewed and kurtotic with vales of 4.53 and 7.43 respectfully which are not between 1.96
and -1.96. Time 15 in the hot environment was not skewed or kurtotic with vales of 0.60
and 0.74 respectfully which are between 1.96 and -1.96. Time 15 in the cold environment
was not skewed or kurtotic with values of 0.83 and 0.54 respectfully which are between
1.96 and -1.96. Time 30 in the hot environment was not skewed or kurtotic with values of
0.10 and 0.31 respectfully which are between 1.96 and -1.96. Time 30 in the cold
environment was not skewed or kurtotic with values of 1.04 and 0.72 respectfully which
are between 1.96 and -1.96.
