okay knocked our feeling hard done by by my previous experiments where I had shown that I look at the graph here shown that a and inhibitor at a hundred micro molar had had no effect no significant effect on the effects of a drug using two-way and over analysis in prison I've repeated the experiment and now I've done a single concentration of our d...

Questions & Answers

Q: What is the purpose of a two-way analysis of variance?

A two-way analysis of variance is used to determine if there is a significant difference between groups when there are two independent variables involved.

Q: How are the vehicle and inhibitor datasets represented in the graph?

The vehicle dataset is represented by dark filled circles, while the inhibitor dataset is represented by lines and symbols.

Q: What does it mean if the analysis reports a significant effect of inhibitor concentration?

A significant effect of inhibitor concentration means that there is a noticeable difference between the inhibitor and the vehicle at certain concentrations.

Q: How are the results of the analysis visually displayed in the graph?

The graph uses stars to indicate the significant differences between the inhibitor and the vehicle at specific concentrations.

Summary & Key Takeaways

• The content demonstrates the process of conducting a two-way analysis of variance to determine if inhibitor concentration has a significant effect on the results.

• A graph is used to visualize the data, with vehicle and inhibitor datasets plotted against increasing concentrations of the inhibitor.

• The analysis reveals that inhibitor concentration has a significant effect on the results at concentrations of 150 and 200.
