OUR TEAMLAB 3A WRITE-UPDescriptive Statistics
For heart rate, the standard deviation of the gold standard (20.50269 bpm) and Spree band (21.46775 bpm) were actually quite similar. This would indicate that the Spree was relatively accurate in measuring heart rate.

Analysis
Summary/DiscussionWhile using the Spree headband, there were a few flaws we noticed with the design of this object. One of the most apparent flaw contained in this headband is the fact that it doesn't measure the exact temperature, but instead gives a range of what the temperature is closest to. This does not create accurate results as it only picks a certain range the temperature is around. The second design flaw noticed in this product is that it measures off temperature based off the user's skin, and not directly. This is not accurate because the skin does not depict the actual temperature of the user, since it can easily be affected by the environmental temperature. Another design flaw noticed while conducting this experiment is that is very uncomfortable and does not stay in place. For this product to be effective, it needs to be comfortable for the user so they wouldn't mind wearing it. To make this product better, there are many steps that can be taken. One measure that can be taken is to make the headband more appealing to the eye so more people would wear it and not mind it looking bad in public. LAB 3B WRITE-UPTarget Population and Need
