Our results were used by other dairy farms to grass feed there cows an hour ahead to produce more gallons of milk.

# data[].attributes.body
Average for fed cows: 4.0
Average for un-fed cows: 3.2
4.0-3.2= .08
Our studies can be useful to the farms so they can produce more milk, so this statistically significant.

# data[].attributes.body
At the end of one week study, we were able to milk fed cows for 4.2 hours and for un-fed cows we were able to milk four 3.5. So the difference was .7.

We are unable to blind the subject since it is an animal and will know that it’s eating. Therefore there will not be a double blind since we now which animal will be fed before milking.

# data[].attributes.body
They were matched by size/weight and randomly picked to be fed grass or not.

# data[].attributes.body
Our control group is the 25 goats who are being fed grass before being milked, so there won’t be a placebo since the other 25 cows wil not be fed at all.

# data[].attributes.body
We picked a big dairy farm and tagged them with numbers (1-25(un-fed cows) and 1-25(fed) ). We then picked randomly selecting 10 from each group. Our potential lurking variables are weight, how much they ate, age, and metabolism.

# data[].attributes.body
Numbering all cows and goats and picking them randomly.

# data[].attributes.body
We will measure how long the un-fed cows and fed cows can be milked for.

# data[].attributes.body
Our experimental variable is if cows that are fed grass before being milked will do better then cows without being fed

# data[].attributes.body
We will make 25 goats eat an hour before getting milked and the other will be fed After it’s milked.

# data[].attributes.body
We will have a total of 25 in-fed cows and 25 fed cows

# data[].attributes.body
Which produces more milk cows or fed cows ??
