have answers with no variability
(there is only 1 answer).

can be answered by data
. Step 2: Determine a plan to collect the data. Step 3: Summarize the data with graphs and numerical summaries. Step 4: Answer the question posed in Step 1 using the data and summaries.
What are the main topics in statistics?
- Combinatorics and basic set theory notation.
- Probability definitions and properties.
- Common discrete and continuous distributions.
- Bivariate distributions.
- Conditional probability.
- Random variables, expectation, variance.
- Univariate and bivariate transformations.
What are some examples of statistics?
A statistic is a number that represents a property of the sample. For example, if we consider
one math class to be a sample of the population of all math classes, then the average number of points earned by students in that one math class at the end of the term
is an example of a statistic.
