If doctors use digital devices to immediately access full in-patient records, modify prescriptions, and arrange changes in diets, hypertensive patients might be able to keep their blood pressure under control more effectively than in hospitals where more traditional procedures are followed. Suppose that an experimenter wants to investigate the effect of cardiologists' use of digital handheld devices on the success that patients have in managing their blood pressure. It's often true that the experimenter cannot manipulate certain aspects of how the hospital manages health care.

For example, some medical research takes place in hospitals. Some experiments rely on settings that are to some degree intact and therefore not subject to experimental manipulation. QI Macros also draws a box plot to help you visualize the results.Ĝompare the difference in Means (color change in the box) and the variation (height of the box and length of the whiskers).Statistical Analysis Using Excel LiveLessons (Video Training)

In the example above, QI Macros built in code compares the p-value (0.000) to the significance (0.05) and tells you to "Reject the Null Hypothesis because p<0.05 (Means are Different/Means are not the Same)."

QI Macros is the only statistical software that tells you if you can Reject or Not Reject the null hypothesis and whether the Means are the same or not the same. When you run ANOVA, you don't have to think like a statistician because QI Macros interprets the results for you.

So, you decide to test this at 5%, 10%, 15% and 20% hardwood concentration levels. You measure the tensile strength in pounds per square inch (PSI). You suspect that changing the concentration of hardwood in the bag will change the tensile strength. Imagine you manufacture paper bags and you want to improve the tensile strength of the bag.
