When they received new clients the last month, they asked if they wanted to be part of a free 12-week program. They verified BMI for us]]> 2017-04-07 04:12:20 UTC https://padlet.com/stephen_coots/yzh7nfiuexwy/wish/165300420 stephen_coots https://padlet.com/stephen_coots/yzh7nfiuexwy/wish/166260848 We had the gym give us a list of 250 people. We numbered them all and uses a random number table to select 125 for the treatment group. Potential lurking variables are metabolism rates, muscle mass, height, and diet. By randomizing we can reduce the impact of these]]> 2017-04-13 14:42:10 UTC https://padlet.com/stephen_coots/yzh7nfiuexwy/wish/166260848 stephen_coots https://padlet.com/stephen_coots/yzh7nfiuexwy/wish/166261536 Our control group is the 125 participants who will NOT have coconut oil in their smoothies.

There is no double-blind either, because our team is small and we all know who is in which treatment group.]]> 2017-04-13 14:55:42 UTC https://padlet.com/stephen_coots/yzh7nfiuexwy/wish/166263507 stephen_coots https://padlet.com/stephen_coots/yzh7nfiuexwy/wish/166272448 We matched up people by gender, height, and body composition prior to the study and randomly picked one to get the coconut oil and one to not get it.
