What is the difference between a mean, median and mode of a
dataset? Provide an example of when it would be appropriate to
report each of these. What is a standard deviation? Why is it
necessary to report both a measure of center and a measure of
spread?
Explain the mean, median, and the mode
2. What is the variance and statistics?
3. What is meant by descriptive statistics and Inferential
statistics?
4. What is the difference between categorical variables and
numerical variables?
5. What is the difference between a population and sample?
6. What is conditional probability?
Find the mean, median, and mode of the following set of data.
(Enter solutions for mode from smallest to largest. If there are
any unused answer boxes, enter NONE in the last boxes.) (a) 6 6 7 8
9 12 Mean Median Mode Mode (b) 6 6 7 8 9 108 Mean Median Mode
Mode
Why Mean, Median and Mode are called centrality
measurements?
Provide an example in which the Median is a better indicator
than the Mean
Why Range, Mean Average Deviation, Variance and Standard
Deviation are called Dispersion Measurements
