Make and Read a Dot Plot

Start with the dot plot page, then the frequency table and histogram pages in order. Use the shape page last to discuss symmetric and skewed data.

Make a dot plot of books 20 students read and find its mode, range and median. A dot plot shows each data value as a dot or X above a number line, so you can see how the data is spread out. The directions on the page read: Make a dot plot of the data. Draw one X above the number line for each value. Then answer the questions. An answer key is included.

Yes, both. We made it for 6th Grade data & graphing, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens with dot plots and histograms. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.

A dot plot shows every single value as a dot. A histogram groups values into intervals, such as 20 to 29, and shows the count for each interval as a bar.

The intervals cover the number line with no gaps, such as 0 to 9, 10 to 19 and 20 to 29, so the bars sit side by side.

A data display is skewed when most values pile up on one side and a tail stretches to the other. Scores on a 15-point quiz that cluster high with a few low scores are skewed left.

Yes. All 5 worksheets have an answer key, including the finished dot plot and histograms.
