    Binomial Population Distributions

    Binomial Distribution - N=4, P=Q=.5


    Distribution of Binomial Scores for 4 coin tosses
    Mean=2 Median=2
    This population is not normal at all.

    Binomial Distribution - N=6, P=Q=.5


    Distribution of Binomial Scores for 6 coin tosses
    Mean=3 Median=3
    This population is a bit closer to normal.

    Binomial Distribution - N=10, P=Q=.5


    Distribution of Binomial Scores for 10 coin tosses
    Mean=5 Median=5
    This population is closer to normal.

    Binomial Distribution - N=30, P=Q=.5


    Distribution of Binomial Scores for 30 coin tosses
    Mean=15 Median=15 StDv=2.7386
    This population is very close to normal.
    The StDv value is the normal approximation.
