How the Ohio State Tests reports it

Ohio's State Tests are Ohio-specific assessments built around Ohio's Learning Standards for Mathematics, which are CCSS-derived and retain the Common Core grade-level domains and (at high school) conceptual categories nearly verbatim. Math is tested in grades 3-8 and via end-of-course exams; the high-school graduation pathway uses Algebra I and Geometry, but students in an integrated sequence take Integrated Mathematics I and II in their place (these integrated courses are not given their own bands here — Integrated Math I draws on the same Algebra/Functions/Number & Quantity/Geometry/Statistics content as Algebra I plus early Geometry, and Integrated Math II adds the remaining Geometry/Functions/Probability content). The reporting categories below are the official math subscore categories Ohio publishes per test; because no public item-percentage blueprint was retrievable, the cluster-level Common Core domains those subscores cover are used (the standards' grade-level domains, which the reporting categories mirror).

Blueprint & weighting

Ohio publishes per-test math subscore (reporting) categories in its Subscore Definitions chart and raw-score subscale ranges, but no public per-category item-percentage blueprint was retrievable; the statistical summaries report the number of items per subscore by administration rather than a fixed blueprint weighting.

Four small data sets are listed below. Which set has the least standard deviation?

Set A: $7, 9, 11, 13$
Set B: $8, 10, 10, 12$
Set C: $5, 10, 10, 15$
Set D: $6, 9, 11, 14$

Set B has mean $10$ with two values at the mean and the others only two units away, giving the smallest standard deviation, about $1.4$ . Sets A, C, and D spread farther from their means.

The distances, in miles, run on seven days are $6\textsf{,}$ $8\textsf{,}$ $12\textsf{,}$ $9\textsf{,}$ $14\textsf{,}$ $7\textsf{,}$ and $14\textsf{.}$ Which data set has the same mean?

The original mean is $\dfrac{6 + 8 + 12 + 9 + 14 + 7 + 14}{7} = 10$ . The set $4\textsf{,}$ $6\textsf{,}$ $8\textsf{,}$ $10\textsf{,}$ $12\textsf{,}$ $14\textsf{,}$ $16$ also has mean $10$ , so the means match.

Five afternoon temperatures, in degrees Fahrenheit, are $64\textsf{,}$ $78\textsf{,}$ $72\textsf{,}$ $60\textsf{,}$ and $66\textsf{.}$ Which data set has the same median?

In order, the original values have middle value $66$ , so the median is $66$ . The set $61\textsf{,}$ $65\textsf{,}$ $66\textsf{,}$ $77\textsf{,}$ $81$ also has median $66$ , so the medians match.

On four science quizzes, Priya earned scores of $85$ , $92$ , $78$ , and $88$ . On a fifth quiz, her score was $x$ . The mean score on all five quizzes is $87$ . What is the value of $x$ ?

Five quizzes with a mean of $87$ total $5 \times 87 = 435$ . Since $85 + 92 + 78 + 88 = 343$ , $x = 435 - 343 = 92$ .

For a normal distribution, approximately what percent of the data lies within $2$ standard deviations of the mean? Use the empirical rule.

By the empirical rule, about $95\%$ of the data lie within $2$ standard deviations of the mean.

A coach records the goals her team scored in seven games: $1, 3, 2, 3, 0, 3, 2$ . What is the mode of the data?

The value $3$ appears three times, more often than any other value, so the mode is $3$ .

Four data sets show minutes spent on homework each night. Which set has the greatest standard deviation?

Set A: $18, 20, 22, 24, 26$
Set B: $19, 21, 23, 25$
Set C: $15, 20, 25, 30$
Set D: $20, 21, 22, 23, 24$

Set C has mean $22.5$ with values stepping by $5$ from $15$ to $30$ , so each value is far from the center; its standard deviation is about $5.6$ . Sets A and B spread less evenly, and Set D is tightly clustered.
