Statistics definitions Bias-Bias is a term which refers to how far the average statistic lies from the parameter it is estimating‚ that is‚ the error which arises when estimating a quantity. Errors from chance will cancel each other out in the long run‚ those from bias will not. Primary data-Data observed or collected directly from first-hand experience. Secondary data-Published data and the data collected in the past or other parties Qualitative data-Qualitative methods are ways of collecting

Investigating the best fabric for science laboratory clothing. (Final Report) Abstract: This experiment looked at the effectiveness of cotton‚ wool and polyester to come up with a hypothesis to which material would be the best used in a lab coat. After the hypothesis was made an experiment was done on the 3 materials‚ to find out which material is the best to use in a lab coat. The results of the experiment were that wool was the best material to be used in a lab coat. Introduction: Scientists and

The different shape and narrowness or width as well as weight distribution are all factors in flight distance. So if I have a narrow paper airplane‚ a very wide one‚ and one in between‚ which on will fly the farthest? * The relevance of this experiment is similar to understanding a real airplane. Paper airplane models are derived from an actual plane these days. The design of an airplane has so much to do with distance‚ hang time‚ speed‚ and many other factors. Understanding the models I have

In my experiment‚ I investigated the question “How does the amount of solute affect the time it takes for the solute to dissolve?” I thought about this question for a very long time and come up with a hypothesis for the investigation was “If the amount of solute increases‚ then the time for the solute to dissolve will increase. This is because the solute will become more concentrated and it won’t disolve into the solvent as fast. (Sadner‚ 2008)” Looking at the data I collected‚ I think that this

It follows that charitable companies should offer a few thank you gifts to increase donations right? Wrong. According to a recent study by George Newman and Jeremy Shen‚ thank you gifts actually decrease charitable donations. Six separate experiments were utilized within this study to explain the counterintuitive phenomenon. Their findings offer support for the motivational crowding theory‚ in which extrinsic motivators such as gifts undermine intrinsic motivation. Shen and Newman initially

Animal experimentation has been a commonly debated subject for many years. There are two aspects for why animals’ testing is wrong. The first aspect is that these experiments would not necessarily work. The other aspect is that these experiments are morally wrong and doesn’t do us any good. Animals should not be used in laboratory experiments. Animal research would not necessarily work. The benefits to human beings are not proven. Doctors might succeed trying a medicine on animals but it might not
