MO MAP Grade 6 Statistics and Probability Practice

Statistics and Probability skills

Develop understanding of statistical variability

Summarize and describe distributions

Summarize numerical data sets in relation to their context

Display numerical data in plots on a number line including dot plots, histograms, and box plots

Standards basis

Missouri Learning Standards (Mathematics K-5 and Mathematics 6-12; revised standards approved April 19, 2016) — Missouri

How the MO MAP reports it

Missouri’s MAP math is built from the Missouri Learning Standards and the state’s item specifications, not from a separate national testing framework. The standards are closely CCSS-aligned in structure, with grade-level and course-level domains used as the native reporting/coverage structure.

Blueprint & weighting

Missouri publishes grade-level and EOC blueprints, but the accessible official pages in this pass did not expose the domain-by-domain percentage tables. The assessment page states that item specifications organize expectations by domains/strands and that blueprints are available for grade-level and EOC assessments.

A clinic recorded customer wait times, in minutes, for $16$ visits. The frequency table shows the results.
$\begin{array}{c|c} \text{Wait time (min)} & \text{Number of customers} \\ \hline 2 & 2 \\ 5 & 3 \\ 8 & 2 \\ 11 & 6 \\ 14 & 3 \end{array}$

What is the median wait time?

Expand to $16$ wait times: $2, 2, 5, 5, 5, 8, 8, 11, 11, 11, 11, 11, 11, 14, 14, 14$ . The $8$ th and $9$ th values are both $11$ , so the median is $11$ minutes.

A student logs five daily page counts: $20$ , $25$ , $30$ , $35$ , and $40$ . A sixth day with $45$ pages read is added to the data set. How does this affect the mean?

The mean of the original five counts is $\dfrac{20+25+30+35+40}{5}=30$ pages. Because $45>30$ , adding $45$ pulls the mean up.

The practice times, in minutes, for five days are $18\textsf{,}$ $22\textsf{,}$ $30\textsf{,}$ $20\textsf{,}$ and $35\textsf{.}$ What is the mean practice time?

Mean $= \dfrac{18 + 22 + 30 + 20 + 35}{5} = \dfrac{125}{5} = 25$ .

Find the mean of the data set 1, 4, 4, 7, 9.

Mean $= \dfrac{1+4+4+7+9}{5} = 5$ .

Seven game scores are $90\textsf{,}$ $70\textsf{,}$ $82\textsf{,}$ $75\textsf{,}$ $95\textsf{,}$ $60\textsf{,}$ and $88\textsf{.}$ What is the median score?

In order, the values are $60\textsf{,}$ $70\textsf{,}$ $75\textsf{,}$ $82\textsf{,}$ $88\textsf{,}$ $90\textsf{,}$ $95\textsf{.}$ The median is the middle value, $82\textsf{.}$

A club answered the statistical question "How many hours did you practice this week?" The answers were $4, 7, 7, 9, 10, 12, 13$ . How many people were interviewed?

Each answer in the list is one person. Count every value, including repeats: there are $7$ answers, so $7$ people were interviewed.

Which of these is NOT a statistical question?

A statistical question anticipates variability: many people or things can give different answers. "How many pets does my family own?" asks about one family, so it has one answer. It is not a statistical question.

A coach recorded how many goals the team scored in each of $16$ games. The frequency table shows the results.
$\begin{array}{c|c} \text{Goals scored} & \text{Number of games} \\ \hline 1 & 2 \\ 3 & 4 \\ 5 & 4 \\ 7 & 3 \\ 9 & 3 \end{array}$

What is the mean number of goals scored per game?

Multiply each goal total by its frequency and add: $(1 \times 2) + (3 \times 4) + (5 \times 4) + (7 \times 3) + (9 \times 3) = 82$ . With $16$ games, the mean is $\dfrac{82}{16} = 5.125$ goals per game.
