A Psychology graduate student conducted a study at the entrance to a footballl gave at the university. The enterance was specifically for studnets who mae\de the Dean's List for academic achievement during the previous semester. Some students arrived to watch the game by themselves, while others arrived in a group. As they arrived, the graduate student asked half of the studnets to record their attendance on the attendance sheet. the remaining half were allowed to enter the game without recording their attendance. The graduate student told every student to take one soda and one hamburger from a concessions table sponsored by the Dean's office. She then returned to the sign-in table out of sight of the concessions. This gave the students the opportunity to take additional food. List the control group, confounding variable, independent variable, and dependent variable.

light-year  

the distance that light travels in a vacuum in one year, equal to about 9.46 trillion km (5.88 trillion mi). light-years are used in measuring interstellar and intergalactic distances.  

parsec  

a unit of distance used in astronomy, equal to about 3.25 light years (3.08 × 1016 meters).  

parallax  

the apparent angular displacement of a celestial body due to its being observed from the surface instead of from the center of the earth (diurnal parallax or geocentric parallax) or due to its being observed from the earth instead of from the sun (annual parallax or heliocentric parallax)  

absolute magnitude  

the magnitude (brightness) of a celestial object as it would be seen at a standard distance of 10 parsecs.  

apparent magnitude  

the magnitude of a celestial object as it is actually measured from the earth.  

redshift  

an increase in the wavelength of radiation emitted by a celestial body as a consequence of the doppler effect.  

the great thing about your imagination is that it doesn't have to make sense! if i were you i would be stuck in space, no communication with earth travelling around and around, you can only guess how long its been since your communication broke down. you land on an undiscovered planet, you do a scientific investigation examining the elements and conditions. you come across alien lifeforms.  

best of luck!
