BUAL 2600 GRAMLING AUBURN FINAL
EXAM QUESTIONS WITH CORRECT
ANSWERS
content analysis - ANSWER-a systematic analysis of the content rather than the
structure of a communication, such as a written work, speech, or film
relative frequency calculation - ANSWER-frequency/sum of all frequencies
consent form should include: - ANSWER-1. Purpose of the data collection 2.
Confidential or Anonymous 3. What participant is expected to do 4. Risk or
discomforts 5. Participation is voluntary (or not) 6. Who to contact if participant has
questions
what makes a graph misleading - ANSWER-- use accurate intervals
- max and min value
- don't combine unequal graphs
dashboard vs report - ANSWER-dashboard- A Data Visualization Tool customized
and tailored to what a business needs to see, interactive, real time
report - historic snapshots
excel commands - ANSWER-mean - Average(A2:A:20)
median - median(A2:A:20)
mode - mode(A2:A:20)
Standard deviation - STDEV(A2:A:20)
how to find range - ANSWER-max-min
how to find skewness by comparing mean and median - ANSWER-left skew : mean
is left of the median
right skewed : mean is right of the median
standard deviation given variance, vice versa - ANSWER-standard deviation is
square root of population variance, variance is square root squared
unimodal, bimodal, multimodal - ANSWER-Unimodal means having one mode. This
is a useful term for describing the shape of a histogram when it's generally mound-
shaped. Distributions with two modes are called bimodal. Those with more than two
are multimodal
finding z score - ANSWER-(x-mean)/standard deviation
68-96-99.7 rule - ANSWER-68% 96% and 98% lie within 1, 2, and 3 standard
deviations of the mean
