State the likely relative positions of the mean, median, and
mode for the following distributions:
Family income in large city
Scores on a very easy exam
Heights of a large group of 25-year old males
The number of classes skipped during the year for a large group
of undergraduate
Provide Mean, Median, Mode, Upper and Lower Limit
Any null or missing values
Detect any outliers or data points of interest
Provide a paragraph for each column with facts from the
previous 3 bullets and provide the business context behind the
importance of the column, showing the analysis and how this helps

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
