Types of Sampling In applications: Probability Sampling: Simple Random Sampling‚ Stratified Random Sampling‚ Multi-Stage Sampling * What is each and how is it done? * How do we decide which to use? * How do we analyze the results differently depending on the type of sampling? Non-probability Sampling: Why don’t we use non-probability sampling schemes? Two reasons: * We can’t use the mathematics of probability to analyze the results. * In general‚ we can’t count on a non-probability

Simple Harmonic Motion Ethan Albers Case Western Reserve University‚ Department of Physics Cleveland‚ OH 44106 Abstract: In this lab‚ my partner and I observed oscillations that were translational and rotational. The two forms we studied must have a form of a restoring force that is proportional to the displacement of the object from its point of equilibrium. This produces the harmonic motion which this lab wants. At small and big amplitudes we measured/observed the translational oscillation

to better it’s elementary education system‚ they progressively eliminate the amount of time spent for physical education. They believe that this approach is necessary to vacate time in the day for more possible time in the classroom learning core subjects; such as math‚ English‚ reading‚ etc. This may seem like a productive way to better educate their pupils‚ but in fact they could be limiting their potential learning capacity by restricting their daily physical education. In children‚ daily physical

There are several types of diffusion‚ but for the purposes of this lab‚ we will be focused on simple and osmosis. Simple diffusion and osmosis are vital for the diffusion of water and maintaining homeostasis. Homeostasis is the ability to maintain equilibrium and keep the organism alive. For example‚ if a cell is placed in a hypotonic solution there is more
