About this resource
What's inside this resource
This dot plots and histograms worksheet gives grade 6 and 7 students ready-made data sets to display, read and compare. On page 1, students plot 16 bean seedling heights on a labeled number line, then find the most common height, the range, a cluster and a gap. Page 2 groups 18 paper-helicopter fall times into equal half-second ranges, has students draw the histogram, and asks them to test a classmate's claim using their counts.
Page 3 asks which display would better answer five different questions, then has students describe two mistakes in a flawed histogram and redraw it. Page 4 matches three drawn displays to descriptions of their shape, including one description that fits none of them, and ends with a short task: collect 10 to 15 class values and choose the better display.
The single answer-key page gives every answer, with model drawings of the dot plot, the histogram and the corrected histogram. All five pages are available in color and in black and white for photocopying.

Teaching tips & learning objectives
Learning objectives
Construct a dot plot and a histogram from a given data set, using equal, non-overlapping ranges for the histogram.
Read a data display to find the mode, range, clusters and gaps, and use counts to test a claim.
Decide whether a dot plot or a histogram better answers a statistical question.
Teaching tips
Approve each student's question before they collect their 10 to 15 answers for the Your data task.
Read the page 2 card about ranges with the class so students see which times belong in 1.5–1.9 before they count.
For Fix the histogram, have students compare Kai's table with his bars row by row before they describe the mistakes.
Skills covered
Building data displays: students plot whole-number data as a dot plot and sort decimal data into equal ranges for a histogram.
Reading distributions: students find the mode, range, clusters and gaps, and use bin counts to judge an "at least half" claim.
Choosing a display: students weigh exact values against grouped ranges for questions about pets, apples, race times, shoe sizes and quiz scores.
Good to know
Questions teachers ask about this resource
Do students need to collect their own data?
Only for the short Your data task on page 4, which uses 10 to 15 class values. Pages 1 to 3 supply every data set.
Are the graph frames already drawn?
Yes. Page 1 has a number line labeled 5 to 19, and the histogram tasks have grids with labeled axes and ranges.
Does it include an answer key?
Yes. The one-page key covers every fixed answer and shows model drawings of the seedling dot plot, the helicopter histogram and Kai's corrected histogram.
What grade level is it for?
It targets grade 6 statistics and also works as review in grade 7.
