WebNov 12, 2024 · The formula used for chi-square tests is χ2 = ∑ (O−E)2 E2 χ 2 = ∑ ( O i − E i) 2 E i 2, where: χ χ is chi Oi O i is the observed value Ei E i is the expected value The … WebJun 15, 2014 · We then do exactly the same for the Bs in the code. The expected number is 162 x 0.015 = 2.43. The actual number is 3. Therefore we can do (3-2.43) 2 /2.43. We do this same method for all the letters A-Z and then add all those numbers together. This is our Chi Squared statistic. The lower the value, the closer the 2 distributions are.
