Each dot is one value, so the tallest stack is the mode and the whole picture is the data set written out. Counting the dots is the step students skip.
A dot plot has 3 dots over 5 and 1 over 8. Find the range
The smallest value is 5 and the largest is 8.
8 minus 5.
The answer is 3.
Where students go wrong
Reading the height of a stack as the value. The height is how many times it happened; the value is the number underneath it.
Also called line plot, dot plot worksheet or reading a dot plot.

Questions about these worksheets
Yes. Every dot plot sheet is free to print and free to download as a PDF. There is no account to make, no email to hand over and no limit on how many you take.
Yes. The answer key prints on a second page, and you can choose whether it shows each question beside its answer or just the answers in a list.
Yes. Print straight from the page, or download the PDF and print that. The sheet is laid out for paper rather than squeezed off a screen, so there is room to work under each question, and the answer key comes out on its own page.
Statistics is usually taken around 11th or 12th grade, though schools vary and plenty of students meet it earlier or later. Pick the difficulty rather than the grade: the easy level suits a first lesson on it, the hard level suits review before a test.
Yes, as many as you like. The questions are built fresh each time rather than picked from a fixed set of files, so pressing Generate gives a new sheet. That is what you want for a second class, a retake, or two students sitting next to each other.
That is the closest comparison, and Kuta Software is good software. It is also paid software you install on a computer. These worksheets run in a browser tab for free, with no account and nothing to install. Like Kuta, the dot plot questions are generated when you ask for them rather than pulled from a fixed set of files, so two classes never get the same sheet, and the answer key comes with it.
Yes. There are three levels, and you can tick more than one for a sheet that mixes them, in which case the questions come out easiest first. The harder levels are not just larger numbers: they ask for something the easy ones do not.
You pick from 4: the mean, the median, the mode and the range. Tick as many as you want and set how many of each, or let it spread them evenly.
