To obtain LC50 and LC90 values using probit analysis in SPSS, first, organize your data with the dose levels and the corresponding binary response (e.g., dead/alive) for each treatment group. Next, navigate to "Analyze" > "Regression" > "Probit" in SPSS, and input your variables accordingly. After running the analysis, check the output for the probit model coefficients, which can be used to calculate the LC50 and LC90 values by determining the doses corresponding to the 50% and 90% mortality probabilities, respectively. You can also use the "Probit" or "Logit" option under "Analyze" to directly estimate these lethal concentrations based on your data.
