Find the mean, median, mode and range of a data set
When to use this goal
For students who confuse the four measures or who can compute a mean with a calculator but forget to order the data for the median. Present levels in ordering numbers and in division decide the support.
- Baseline
- Score each measure separately; the median with an even number of values and sets with no mode or two modes are the specific cases to include. Note whether the student orders the data before finding the median.
- Tips
- The student's own scores and data are the most meaningful sets. Ordering first is the taught habit that prevents most median errors.
- Limits
- Computing the measures does not show the student knows which one to use or what it means for the data. Calculator use is assumed for the mean.

Goal
By the annual IEP review date, given 10 data sets of 5 to 9 whole numbers, with a calculator, the student will write the mean, median, mode and range for each data set independently with at least 85% accuracy on measures, on 3 of 4 consecutive probes, as measured by work-sample analysis collected every two weeks.
Baseline: 30% accuracy.

Measurability check11 of 11 met
Met: Observable behavior. Stated as an action.
Met: Condition. Stated.
Met: Unit fits the behavior. Percent accuracy fits this behavior.
Met: Explicit criterion. Number and unit stated.
Met: Mastery rule and schedule. Both stated.
Met: Method produces the metric. Work-sample analysis gives percent accuracy data.
Met: Review timeframe. Stated.
Met: Baseline and target compatible. Same unit, change in the right direction.
Met: Aligned with area of need. Still about Patterns, Data & Graphs.
Met: Level of support. Defined.
Met: Blanks filled in. Nothing left to fill in.
Checks structure and wording only. Whether the goal fits the student is the team's call.
Short-term objectives (optional)
When are objectives required?Required for students on alternate assessments (34 CFR §300.320(a)(2)(ii)); some states require them for everyone.

- Score only items the student attempted unless the goal defines a fixed set of items. Use the same denominator every session.
- Percent = numerator ÷ denominator × 100. Round to one decimal place.
- Record the support actually provided, even if the goal is independent performance.
