So....statistical tests are like tools for telling if a trend is a real trend or if an event just falls within what we would expect of natural variation. However, since there are all sorts of different types of trends that we want to look at there are different types of statistical tools to look at those trends and they are not interchangeable in the same way that a hammer and a saw are not interchangeable.

Sometimes we want to see how well the actual data we observe aligns with certain ratios or amounts that we expect to have happen (ex. the flipping of a penny) For this task we need a goodness of fit test call the Chi squared (pronounced KAI SQUARED).

Question: If a deck of cards is sorted by suit (all hearts, then all clubs etc.) How many rounds of shuffling is required to achieve a random distribution of the suits throughout the deck?

To support your Chi squared test you will use a guidance sheet.
