Experimental bias

Instrument effect

The instrument effect is an issue in experimental methodology meaning that any change during the measurement, or, the instrument, may influence the research validity. For example, in a control group design experiment, if the instruments used to measure the performance of the experiment group and the control group are different, a wrong conclusion about the experiment would be reached, the research result would be invalid.

AWESOME Physics demonstration. Coriolis effect (explained)!!!

The Coriolis effect refers to the apparent deflection of objects (such as airplanes, wind, missiles, and ocean currents) moving in a straight path relative to the Earth's surface. Its strength is proportional to the speed of the Earth's rotation at different latitudes. For example, a plane

Teach Astronomy - Doppler Effect

http://www.teachastronomy.com/ The Doppler Effect is the shift of wavelength or frequency of a source of waves due to the motion of that source of waves. Doppler Effect is most familiar in terms of sound waves. As a source of sound, such as a siren, approaches you, the pitch or frequency
