Negative value: Absolute Risk Increase. ** For Relative Risk Reduction (RRR): Positive value: Relative Risk Reduction. Negative value: Relative Risk Increase. Can you have a negative rate difference? If your calculation results in a negative percentage, the minus sign can be ignored. For example, if you get a percentage differenceRead More →

The acceptable margin of error usually falls between 4% and 8% at the 95% confidence level. While getting a narrow margin of error is quite important, the real trick of the trade is getting that perfectly representative sample. What does a margin of error tell us? Margin of errors, inRead More →

When forward bias voltage is low, the conduction states on either side of the junction barrier are closely aligned. But as this voltage rises, the conduction states on either side become misaligned. For this reason, the current flow drops as the voltage rises, giving the device a negative resistance differential.Read More →
Convex lens converges incident rays. Hence the rays to converge at a point in front of the lens. So image distance is positive here. We can easily clarify that the focal length is positive direction for a Convex lens while negative with concave lens. What is the sign of focalRead More →
