    Help with stem and leaf plots: mean, median, range, mode, and quartile?
    I've this much done, but haven't been able to find the quartile. Can you help? And tell me if I have gotten the mean, median, range, and mode right?

    Math Test Scores

    Stem| Leaf
    5 | 1 3 5 9
    6 | 1 6 9
    7 | 4 6
    8 | 0 1 2 4 4 4 9
    9 | 2 2 3 6

    Range: 45
    Mean: 76.4
    Median: 80.5
    Mode: 84

    Is all the above right? And how can I find the quartile?

    I'm getting 76.05 for the mean. Check your calculation again.

    Then, there are 4 types of quartile...
    First quartile, second quartile (also mean), third quartile, and interquartile range.
