Create a stem-and-leaf diagram from the following data, and then use it to answer questions 8, 9, and 10. 97, 83, 86, 93, 50, 97, 69, 82, 87, 99, 75, 100, 80, 95, 89, 72, 80, 86, 73, 87, 82, 62, 93, 60, 71, 62, 57, 51, 92, 24, 64, 77, 79, 48, 65, 53, 79, 78, 92, 62, 79, 78, 56, 82, 69, 94, 47, 88, 88, 87, 98, 79, 74 How would you describe the spread? A. Skewed low (most students failed) B. skewed high (most students got A's) C. clustered towards the middle (most students got B's & C's) D. Two or more different peaks Which score is an outlier? Which score lies exactly in the middle?

97, 83, 86, 93, 50, 97, 69, 82, 87, 99, 75, 100, 80, 95, 89, 72, 80, 86, 73, 87, 82, 62, 93, 60, 71, 62, 57, 51, 92, 24, 64, 77, 79, 48, 65, 53, 79, 78, 92, 62, 79, 78, 56, 82, 69, 94, 47, 88, 88, 87, 98, 79, 74
How would you describe the spread?
Skewed low (most students failed)
skewed high (most students got A's)
clustered towards the middle (most students got B's & C's)
Two or more different peaks
Which score is an outlier?
Which score lies exactly in the middle?
Steam and leaf plot is the graphical representation of the data set. It has two parts, they are steam and leaf. Leaf is the last digit of the value and steam is the first digit of the value. It helps to understand the skewness exist in the data set. they are right and left skewness.
