Look at the . If the 95% CI includes the number 1.0 (e.g., 0.95 to 4.2), the effect is generally considered not statistically significant at the 5% level. 5. Visualizing Your Data

Great for comparing individual category counts side-by-side.

χ2 = Σ [(observed frequency - expected frequency)^2 / expected frequency]
To perform a verified chi-square test in , you must enter your data into a Contingency Table using actual counts of subjects, not percentages or averages . Step-by-Step Guide for Chi-Square in Prism ) that would occur if there were no
If you enter percentages (like 45% and 55%) instead of actual patient or sample counts (like 45 and 55), Prism's math will treat your sample size as exactly 100, artificially altering your statistical power and inflating or deflating your P-value.
You must enter raw counts (frequencies) . Never enter percentages, normalized values, or mean values into a contingency table. Chi-square calculations rely strictly on the total number of subjects.
