## Effect of exercise on body temperature

Our hypothesis was that exercise will have no effect on body temperature. We recorded a mean resting temperature of 98.24 ºF, and mean temperatures of 97.99 ºF and 98 ºF for the first and second 1-minute sets of jumping jacks respectively. There was a 0.24 ºF drop in temperature after the first set and a 0.25 ºF drop after the second set, which shows that our hypothesis was not supported by the data. There was relatively low variation within the data, with a standard deviation of 0.93 for body temperature at rest, and standard deviations of 0.76 and 0.75 for each respective set of jumping jacks. This finding was supported by the data acquired by the rest of the class: across the data acquired by all four groups, the mean body temperature was 98.59 ºF at rest and 98.26 ºF after both sets of jumping jacks, with standard deviations of 0.86, 0.77, and 0.82 respectively. There was less variance in the forehead temperatures after each set of exercises than the forehead temperatures at rest.
