Stem and leaf generator7/23/2023 Let’s make a stem and leaf plot of this data We will follow some steps through an example: Lower and larger values are at low frequency or rare in our data. The data are clustered at 9s,11s, and 14s or from 9.0 to 14.9.ĩ.0 is the minimum value for row 9 to represent, and 14.9 is the maximum value for row 14 to represent. There is no other value that is repeated more than that. There are 4 sevens beside 9 so the mode in this data is 9.7 because it is repeated 4 times. Look at the last row to get the maximum of our data.Look at the first row to get the minimum of our data.We look at the key, the stem represents the single values and the leaf represents the decimal values.Lower and larger values are at low frequency or rare in our data.Īnother example, the following is a stem and leaf plot of 30 wind measurements in miles per hour (mph) in New York City. The data are clustered at 15s and 16s or from 150-169.ġ50 is the minimum value for row 15 to represent and 169 is the maximum value that row 16 can represent.ġ5 has 11 numbers in its row and 16 has 13 numbers in its row. Look at the crowded rows to see where the main cluster of data.There are 4 zeros beside 16 so the mode in this data is 160 cm because it is repeated 4 times. Look at the most frequent value in each row to get the most frequent value in our data or the mode. ![]()
