1. Calculate chi-squared (X²) using the equation:

X2=(Observed Value - Expected Value)2Expected Value

1. Record X² and all calculations in Panel 1.

Panel 1: Chi-square Calculation for Millet Seeds

1. Determine the degrees of freedom and record in the Data Table 4.

Data Table 4:Millet Seed Chi-square Test

Conclusion

1. Use the chi-square distribution tableto determine the range of the p-value.

Note: If the value is outside values listed in the table, record as < or > the nearestvalue in the table.

1. Record the p-value in the Data Table 4.
2. Compare the recorded p-value to the benchmarkp-value of 0.05todetermine if there was a statistically significant difference between the expected and observed results.
3. Record your conclusions inData Table 4.
