A stem and leaf plot is a device for presenting quantitative data in a graphical format, similar to a histogram.

Step 1: In a stem-and-leaf plot, the number of data items is equal to the number of leaves present.   

Step 2: Number of leaves present in the above stem-and-leaf plot = 17.

Step 3: So, 17 data items are present in all.
