Describing the shape and nature of a distribution of scores is
a basic skill any researcher needs to inform a lay audience.
Changes in skewness and Kurtosis can happen with particular kinds
of data. Give an example of what could happen during data
collection that can create each kind of change from a standard
normal curve that is listed below.
A positively skewed distribution:
A Leptokurtic distribution:
Explain the different hypothesis tests one could use when
assessing the distribution of a categorical variable (e.g. smoking
status) with only two levels (e.g. levels: smoker and non-smoker)
vs. more than two levels (e.g. levels: heavy smoker, moderate
smoker, occasional smoker, non-smoker).
Be precise. Use the language of the textbook to identify the
appropriate test and how you would conduct it. NOTE: Minimum of 150

1. When the shape of the distribution of scores is normal, which
of the follow is true:
A.) mean < median < mode
B.) mean = median = mode
C.) mean > median > mode
2. When the score for the mean is significantly larger than the
median score, you would expect the shape of the distribution of
scores to be
A.) need more information
B.) positively skewed
C.) negatively skewed
D.) platykurtic
E.) leptokurtic
A property of the t-distribution is that the distribution's
shape remains constant for different degrees of freedom. Group of
