The ones that don’t, the outliers, were most likely caused by extraneous variables. The people whose heart rate was higher before rather than after could have been caused by them doing some sort of physical activity earlier, like riding their bike or walking. This might have been prevented if the test was held a few minutes after they got to the testing site, instead of as soon as they got there. Another factor may have been the tool used to measured. The tool used to measure heart rates was an Apple Watch. The watch may not have taken the heart rate correctly, although on preliminary tests it did. These two influences may have been the most prominent extraneous variables that altered the data. Overall, the extraneous variables should have been considered for more accurate tests. Most of the data was correct, and was enough to make an actual conclusion to the experiment. All things considered, the experiment was a moderate success. The testing went pretty smoothly, and most everything, excluding the few outliers, went according to plan. If the experiment was conducted again, the extraneous variables would have surely been taken care
