Build a differentiated box plots assessment for Year/Grade 6-10 students in minutes. Tutero generates diagnostic, formative and summative tasks covering the five-number summary, interquartile range, outliers, parallel box plots and comparing distributions — auto-graded, curriculum-aligned and ready to print or run digitally.

A diagnostic that pinpoints exactly where each student sits across the box plot strand — from reading a single five-number summary off a plot to comparing the spread of two distributions and justifying which data set is more variable.


Printable summative tests aligned to the Australian Curriculum (v9.0) and Common Core (6.SP and 8.SP). Each assessment moves from labelled-diagram reading through calculating Q1, median, Q3 and IQR, to identifying outliers using the 1.5 × IQR rule and constructing a box plot from raw data.
Scaffolded problem-solving tasks that step students from a single labelled box plot up to parallel box plots and a written comparison of two data sets. Three difficulty levels generate from the same standard so a Year/Grade 6 child finding the median and a Year/Grade 10 child interpreting overlapping distributions can both attempt the same paper.

Item-level analytics show exactly which sub-skill each student missed — confusing median with mean, reading the wrong quartile off the box, forgetting to order the data before finding Q1 and Q3, miscalculating IQR, or flagging a value as an outlier without applying the 1.5 × IQR test. Group dashboards highlight class-wide misconceptions so your next lesson targets the real blocker.
Students answer on paper or on a device. Digital responses are auto-marked and the live results stream lets you see, mid-lesson, who can construct a box plot from raw data and who still needs another go before you move on. Print runs include diagram-ready grids so students can draw plots cleanly without graph paper.
Every result feeds into a recommended next lesson. If half the class is shaky on quartiles, Tutero queues a focused warm-up on ordering data and finding Q1, Q2, Q3 plus a small-group reteach using a worked example. You move from data collection to instructional response inside the same tool.

The Five-Number Summary and Constructing a Box Plot
Before a student can interpret a box plot, they need to build one. A strong assessment asks students to order a raw data set, find the minimum, Q1, median, Q3 and maximum, and draw the box and whiskers to scale on a number line. Tutero generates differentiated versions: Year/Grade 6-7 students work from small data sets of 10-15 values with whole numbers, Year/Grade 9-10 students work with larger sets, decimals, and data presented in frequency tables. Every diagram is auto-checked for the right box position, the right median line, and correctly placed whiskers.
Interquartile Range, Outliers and the 1.5 × IQR Rule
This is where most students lose marks. A solid assessment tests IQR calculation (Q3 minus Q1), uses IQR as a measure of spread, and applies the 1.5 × IQR rule to flag outliers above Q3 + 1.5 × IQR or below Q1 minus 1.5 × IQR. Tutero builds short structured items (calculate the IQR, list any outliers) alongside multi-step questions where students must justify whether a single extreme value should be excluded. Auto-grading catches the common error of using range instead of IQR, and analytics surface which students need a reteach on the 1.5 × IQR boundary specifically.
Comparing Distributions With Parallel Box Plots
The reasoning extension. Students compare two or three box plots drawn on the same scale and answer in full sentences: which data set has the higher median, which has the greater spread, which is more symmetric, and what does the overlap of the two boxes tell you about the populations. Tutero generates real-context comparisons — test scores between two classes, reaction times for two age groups, rainfall across two cities — so students practise statistical reasoning, not just plot reading. Written responses are flagged for your quick review while the numerical comparisons auto-mark, so marking time goes to the thinking, not the arithmetic.
