    Suppose you flip a coin 100 times, and it turns up heads 70 times. Is the coin
    fair? Suppose you roll a die 100 times, and it shows 30 sixes. Is the die
    loaded?
    
    In statistics, the chi-square test calculates how well a series of numbers fits
    a distribution. In this module, we only test for whether results fit an even
    distribution. It doesn't simply say "yes" or "no". Instead, it gives you a
    confidence interval, which sets upper and lower bounds on the likelihood that
    the variation in your data is due to chance.
