    Collect data consisting of at least 20 values. (You may also create a data set with reasonable values for your variable).
    The values are given represent the weights of the 20 kids in the first grade class room:
    36, 36, 37, 37, 38, 38, 41, 41, 41, 42, 42, 42, 42, 43, 44, 44, 44, 45, 45, 45,
    a.Define the variable - the weight in pounds - it is a dependent variable.
    b.Find the mean, median, mode, variance, and standard deviation for your data.
    Mean - 41.15
    Mode - 42
    Variance =

    Please help me figure out the variance and standard deviation to this scenario.
