How the WY-TOPP reports it

WY-TOPP is Wyoming’s statewide summative assessment and, as of 2026, its math blueprint was updated alongside reduced Wyoming content and performance standards. The official assessment page places WY-TOPP within the Wyoming Statewide Assessment System rather than a multi-state framework like SBAC.

Blueprint & weighting

Not found in the official pages reviewed. The official assessment page and 2026 memo confirm updated blueprints, but the specific math domain weights/percentages were not visible in accessible source content.

The table shows quiz scores and how many students earned each score.
$\begin{array}{c|c} \text{Quiz score} & \text{Number of students} \\ \hline 62 & 2 \\ 68 & 3 \\ 74 & 5 \\ 80 & 3 \\ 86 & 3 \end{array}$

What is the median quiz score?

There are $16$ scores. Listing every score from least to greatest, the $8$ th and $9$ th values are both $74$ , so the median is $74$ .

Students answered the statistical question "How many books did you read this summer?" The data are $2, 5, 6, 9$ . What is the range of the data?

The range describes the spread: greatest value minus least value. $9 - 2 = 7$ .

A student is writing questions about trees. Which of these is NOT a statistical question?

A statistical question anticipates variability: many people or things can give different answers. "How tall is this specific tree?" names one tree, so it has one answer. It is not a statistical question.

A runner logs five lap times, in seconds: $18$ , $20$ , $22$ , $24$ , and $26$ . A sixth lap time of $16$ seconds is added to the data set. How does this affect the mean?

The mean of the original five times is $\dfrac{18+20+22+24+26}{5}=22$ seconds. Because $16<22$ , adding $16$ pulls the mean down.

Seven game scores are $14\textsf{,}$ $18\textsf{,}$ $10\textsf{,}$ $20\textsf{,}$ $12\textsf{,}$ $15\textsf{,}$ and $23\textsf{.}$ What is the mean score?

Mean $= \dfrac{14 + 18 + 10 + 20 + 12 + 15 + 23}{7} = \dfrac{112}{7} = 16$ .

Find the mean of the data set 3, 8, 10.

Mean $= \dfrac{3+8+10}{3} = 7$ .
