1. Everyone in the class should flip a coin 2x and record the result. 2. Fair coins are expected to land 50% heads and 50% tails. For example, let's say that the class size 24, 50% of 48 results should be 24. Hence, 24 heads and 24 tails should be written in the "Expected" column. 3. As a class, compile the results in the "Expected" and "Observed" column. 4. In the last column, subtract the expected heads from the observed heads and square it, then divide by the number of expected heads. 5. In the last column, subtract the expected tails from the observed tails and square it, then divide by the number of expected tails.

1. Everyone in the class should flip a coin 2x and record the result. 2. Fair coins are expected to land 50% heads and 50% tails. • For example, let's say that the class size 24, 50% of 48 results should be 24. Hence, 24 heads and 24 tails should be written in the "Expected" column. 3. As a class, compile the results in the "Expected" and "Observed" column. 4. In the last column, subtract the expected heads from the observed heads and square it, then divide by the number of expected heads. 5. In the last column, subtract the expected tails from the observed tails and square it, then divide by the number of expected tails. V Tacloban College-DNSM 6. Add the values together from the last column to generate the X² value. Compare the value with the value at 0.05 with DF=1. 7. • There are 2 classes or categories (head or tail), so DF=2-1=1. • Were the coin flips fair (not significantly deviating from 50:50)? Heads or Tails Heads Tails Expected Observed (Observed-Expected)² Number Number Expected (Observed-Expected) Bio 140.1: Elementary Genetics Laboratory x²=[" Expected 2
