Opening Weekend Gross Sales After calculating several central tendency measures (mean‚ median‚ and mode)‚ one can create a histogram and see the opening weekend gross sales are heavily skewed to the right. The median opening gross sales of 0.39‚ indicating 50% of the opening gross sales values were less than 0.39 and 50% were greater than 0.39‚ would be a more appropriate central tendency measure than the mean due to this skewness (3.43). The range of opening gross sales was 108.43‚ from 0.01

Gravimetric Analysis of a Chloride Salt CHEM 1001 Purpose: To illustrate typical techniques used in gravimetric analysis by determining quantitatively the chloride content in an unknown soluble salt. Theory: AgCl(s) is a very insoluble solid‚ yet still does have some solubility. Because of these traits‚ the following reaction is able to occur: Ag+(aq) + Cl−(aq) → AgCl(s) . This reaction is able to occur in both directions. When a soluble silver salt such as AgNO3 is added to a solution containing

If you cannot master a skill in a year‚ it just means that you need 19 years more. However‚ the research conducted by Ericsson was quite inaccurate: the difficulty of a skill and strengths of a person who wants to acquire it were not taken into consideration. In

Shannon Wood 11/21/2012 Joel‚ Griffin‚ Blake Section #005 ISP 217L Lab 4- Phosphorus Where Does Phosphorus Go? My hypothesis is that dissolved Phosphate will change for the total phosphorus when left under a light. I believe that suspended phosphorus has the biggest impact on the eutrophication of lakes. When there is an increase of phosphorus in lakes‚ this leads to and increase in phytoplankton. This then leads to a decrease in water clarity. The reason that this is relevant is because

are mean‚ median‚ and mode. Mean is “a measure of central tendency that offers a general picture of data without inundating one with each of the observations in a data set” (Sekaran‚ p. 396‚ para 3). A more common term for mean is average. The median is “the central item in a group of observations when they are arrayed in ascending or descending order” (Sekaran‚ p. 396‚ para 5). Mode is the “most frequently occurring phenomenon” (Sekaran‚ 396‚ para 6). The following table shows the mean‚ median
