HW#15c -- Thursday, Jan. 11th

For each experiment, first list the independent and dependent variables. Then, continue the story by describing an experiment that the person could do. In your description, show that the person got data that ended up supporting their original hypothesis. Use complete sentences!

Ex. -- 'Bowling experiment'
Mr. Kitchen thinks that if he eats a large order of fries before he bowls, that
his score will improve. He believes this because he often feels like his hunger
is distracting him.

Mr. Mikulski writes, as his answer to this question:

"INDEP: eating fries or not eating fries
DEP: score per game
Mr. Kitchens alternates either eating fries or not eating fries before his
bowling games, for the next two months. In the 49 games he bowled without the
fries, his average score was a 148. In the 50 games he bowled with fries, his
average was a 164."

------------------------------------

1) Mr. Mikulski believes that if he makes his students keep a good notebook and check online for their assignments, that more of them will be able to succeed (ie, graduate on time from) the college that they later attend.

2) Alan (a student) is pretty sure that the worse a student's attendance is, the worse their grades will be. He surveyed five students in a small experiment.

3) The security guard thinks that if he starts asking students to tuck in their uniforms nicely ("Could you please tuck your shirt in?") instead of sternly ("Tuck in your shirt, man! You know better!"), that the number of students with untucked shirts will increase.

4) Mr. Horton believes that his weight will decrease if the teachers start getting a weekly basketball game going.

5) Janelle thinks that the Chicago police P.O.D.S. (the flashing blue cameras) make the amount of on-the-street crime that happens further down the block increase.
