Average Readiness Mean Median Mode

Print: Ages 8–9 · 2–3 min · Core · Most frequent weight · Independent practice · Choose one weight

Watch: Watch whether the learner checks every record before choosing. Selecting 800 g shows a size comparison; selecting 350 g shows that the learner noticed repetition but stopped before comparing all frequencies.

Misread: The likely misread is choosing the greatest weight or the first repeated weight instead of the weight shown on the most records. A response of 3 or 7 gives a count rather than the requested weight.

Curriculum: This task develops data-analysis readiness by grouping equal values, counting each value’s frequency, and selecting the unique mode from a finite dataset. Scoring checks the chosen unit-bearing value, not an explanation.
