Select the test statistic.
Unless your goal is to somehow improve on what is already written, or you simply don't have those existing tools, then you should never be reinventing the wheel. Use existing code, for example, regress is in the stats toolbox. Or you could even use my polyfitn ...
Calculate the expected frequency for each outcome and record it. The expected frequency is the number of people or objects you would expect to achieve the outcome by chance. To calculate this statistic, multiply the column total by the row total and divide by the total number of observations. ...
Use the standard normal table to see the value of the Z-score in proportion to the area between the mean and a given Z-score and the area beyond a given Z-score. The values on a standard normal table represent values under the standard normal curve. ...
Of course, to compute the p-value, you'd also need to simulate the distribution of the test statistic under the null (and I haven't discussed how one might deal with zero-counts inside the range of values). This should yield a reasonably powerful test. There are numerous other alternative...

The p-value approach to hypothesis testing uses the calculated probability to determine whether there is evidence to reject the null hypothesis. This determination relies heavily on the test statistic, which summarizes the information from the sample relevant to the hypothesis being tested. The null h...
or knownprobability distributionof the specific statistic tested. P-values are calculated from the deviation between the observed value and a chosen reference value, given the probability distribution of the statistic, with a greater difference between the two values corresponding to a lower p-value....
