And I should have a significantly lower heart rate than before. This result means that I almost doubled my capacity to run. But during the last six weeks, I have accumulated at least 50 points per week. I had run a consistent 30-points per week last August and September 2013. Is this significant? Result of the t-test Notice that the mean heart rate during the last six weeks (i.e., 50.28) is lower than that obtained six months ago (i.e., 53.78). This result signals me to go on with the t-test analysis. Given the results of the analysis, I can use the t-test. If it is 0.06 or higher, then the difference in variance is not significant. How do you know that the difference in variance in the two groups of data using the F-test analysis is not significant? Just look at the p-value of the data analysis output and see whether it is equal to or below 0.05. This output means that one group of data does not vary more than the other.
Notice that the p-value for the test is 0.36. F-test analysis using the Analysis ToolPak. Here’s an output of the F-test using the Analysis ToolPak of MS Excel:įig. If no significant difference is detected, then you can go ahead with the t-test. How do you make sure that this may not be the case, that is, that one group of data varies more than the other? The appropriate test to use is an F-test. Nonparametric statistical tests such as the Mann-Whitney U test should be used instead. If they do, then you should not use the t-test. Does one group of data vary more than the other? The Importance of an F-testīefore applying the t-test, the first test you should do to avoid a spurious or false conclusion is to test whether the two groups of data have a different variance. These are the assumptions of this t-test analysis and the reason for choosing the sample size. And the trend line in the graph I previously presented shows that my heart rate slows down through time. I started aerobic running eight months ago. I figured out eight months would be a sufficient time to effect heart rate change. So that’s six weeks times three equals 18 readings. Thus, I thought my heart rate within six weeks should not change significantly. Kenneth Cooper, the aerobic training effect could be achieved within six weeks. I measured my heart rate upon waking up (measuring at this time ensures that I am well rested) during each of my three-times a week aerobics sessions.Īccording to Dr. I will use the Student’s t-test to analyze 18 readings taken eight months ago and the last six weeks as data for comparison. Statistical Question: Is there a significant difference in heart rate eight months ago and last six weeks’ record? Now, I would like to answer the statistical research question I formulated below: I did not test whether there is a significant difference in my heart rate, from the time I started measuring my heart rate compared to the last six weeks’ data. In that article, I used the graphical method to plot a trend line. Thus many athletes have lower resting heart beats per minute than non-athletes.
