In other words:X2 = Σ(sum of) (Observed Value- Expected Value)2 (Expected Value)Procedure:Write your procedure in stepsData Table 1: Number of candies observed and expectedPlace your first data table (copy from excel and paste here)Data Table 2: Chi Square table of candiesPlace your second data table (copy from excel and paste here) Summary and Analysis:1. What was your initial hypothesis?2. How do show that your hypothesis is correct (or correct)?3. Explain what is meant by a “good fit”?4. Propose a way that a chi square analysis could be used in other experiments, such as genetics or drug trials?Student Rubric211518627377400-56362936654200Student Example:TaskPoints PossiblePoints EarnedChi-Square Completed10Accurately determined to accept or reject hypothesis5Explanation of accepting or rejecting hypothesis5Insert graphs of observed and expected10Total30 ................
