Objective:

• Finish your Chi-Squared Calculations

​Resources:

1. Chi-Squared Project Outline
2. Exemplars from last year
   1. Exemplar 1
   2. Exemplar 2
   3. Exemplar 3
3. Chi-Squared Project Template
4. 2024 Math 10 Data

Calculating Chi-Squared Directions.

1. Open your spreadsheet with your calculations for your data

2. Create a Chi-squared Table that matches the number of colored cells for your observed and expected tables
​
3. Use the chi-squared formula and find the chi-squared for each of your data data points

4. Create a final calculations table with Final Chi-Squared, Degree of freedom, Critical Value, P-value

5. Take the sum of each individual chi-squared in the “Final Chi-Squared” cell

6. Find the Degree of Freedom for your data. DF = (n-1)*(n-1) from your expected table. 

7. Use this table to find the critical value for your data. Input the appropriate critical value in your table. 

8. Calculate the p-value by selecting the observed values, and the expected values
