... values. Contingency Table Perpetual set study using the Leeper Lady stimulus Young Face Old Face Marginal Totals Young People 1 0=32 E=26.09 2 0=1 E=6.9 33 Older People 3 0=33 E=41.9 4 0=17 E=11.09 53 Marginal Totals 68 18 Grand Total 86 E values are calculated by multiplying marginal totals and then dividing by the grand total. Cell 1 33x68/86 = 26.09 Cell 2 33x18/86 = 6.9 Cell 3 68x53/86 = 41.9 Cell 4 18x53/86 = 11.09 Chi-squared formula X = (0-E) /E for each cell. Cell 1 (32-26.09) /26.09 = 1.3 Cell 2 (1-6.9) /6.9 = 5.0 Cell 3 (36-41.9) /41.9 = 0.8 Cell 4 (17-11.09) /11.09 = 3.1 Summation of Chi-Squared = 10.2 Degrees of freedom are calculated by taking (row1) from (column 1) (2-1) (2-1) 1x1 = 1 Degree of freedom Calculated value = 10.2, DF = 3.84 Therefore the results are significant and the hypothesis is accepted whereas the null hypothesis is rejected.
