Learn about different ways of collecting, recording, organising and interpreting data. Why is a stem and leaf plot better than a box plot? Look STEM education focuses on helping students develop critical thinking and innovation skills, which is what they will need to succeed after high school. For example, for the data value, 17.4, the stem will be 17, and 4 will be the leaf. at the range of temperatures at the end of the whiskers. Similarly, a stem and leaf plot is similar to a histogram but is usually provide more information for a relatively small data set. Therefore, we will 4 4 in the row of 17 stem to get. Example: For the above example add 23 female students books reading data. The advantage of a stem leaf diagram is it gives a concise representation of data.
