Question
(e) (1 point) If the median is greater than the mode for a data set, what can you conclude about the data's distribution? (1 point) What does the standard deviation represent conceptually in words? (Be concise but don't simply state the equation in words verbatim.) (f) (g) (1 point) Give an example of sampling error? (h) (2 points) A box plot is a useful tool that can quickly communicate many traits about a set of data. List 4 useful pieces of information that an observer can easily assess using a box plot. (G) (1 point) You scored in the 78th percentile on the GRE. If 8,000 people took the GRE, how many people had a score at least as high as your score? Points earned: / 10 pointsExplanation / Answer
e) If median is greater than mean than distribution is skewed to left.
f) standard deviation represents the amount by which every value within a dataset varies from the mean.It indicates how tightly the values in the dataset are bunched around the mean value.
g) sampling error example : Faulty selection of the sample. For example purposive or judgement sampling in which the investigator deliberately selects a representative sample to obtain certain results.
h) 4 useful pieces of information are
minimum value of observation
maximum value of observation
median of data
nature of distribution of data and outliers
