Exam Questions and CORRECT Answers
error bars - CORRECT ANSWER - Graphical representation of the variability of data
mean - CORRECT ANSWER - average
standard deviation - CORRECT ANSWER - a measure of variability that describes an
average distance of every score from the mean
normal distribution - CORRECT ANSWER - A function that represents the distribution of
variables as a symmetrical bell-shaped graph.
Small standard deviation means - CORRECT ANSWER - Data is clustered tightly around
mean
-Less score variety
-More reliable/accurate than large standard deviation
large standard deviation means - CORRECT ANSWER - Data is more spread out and
further away from mean (wider spread)
-More score variety
-Less reliable than a small standard deviation
coefficient of variation - CORRECT ANSWER - A measure of relative variability
computed by dividing the standard deviation by the mean and multiplying by 100.
Specificity - CORRECT ANSWER - Making sure aspects of the study are connected to the
activity
Choosing appropriate warm-ups and tasks for our measurements
, MGRADES
Accuracy - CORRECT ANSWER - Using equipment which will provide us with accurate
information
Must make sure equipment is working properly
Reliability - CORRECT ANSWER - Must consider other aspects and individual
differences which could alter results
Validity - CORRECT ANSWER - Need to repeat experiment multiple times in order to
improve validity
More results can allow more reliable and accurate statistics for evaluation
importance of study design in the context of the sports, exercise and health sciences - CORRECT
ANSWER - Causality in experimental results by the inclusion of:
control in groups
randomization
placebos
blinding and double-blinding
statistical analysis
Importance of PAR-Q - CORRECT ANSWER - Assesses the readiness for an individual
to partake in a general training program
Laboratory Tests advantages - CORRECT ANSWER - Controlled environment
Stimulate sport's demands
Sport specific equipment
Laboratory tests disadvantages - CORRECT ANSWER - Not in sport environment
Not always accessible
Limited value assessing team sports
