The materials used for this lab were filter papers‚ a choice chamber‚ eight pill bugs‚ water‚ and tin foil. The first step of the process is to trace and cut the filter paper so it fits neatly within each side of the choice chamber. Then‚ put water each filter paper and place the damp filter paper into the choice chamber. The damped filter paper causes the pill bugs to not be able to crawl under the paper and therefore disrupting the results. Four pill bugs should be placed on either side and one

Graphical and Simplex Methods of Linear Programming The graphical method is the more popular method to use because they are easy to use and understand. Working with only a few variables at a time they allow operations managers to compare projected demand to existing capacity. The graphical method is a trial and error approach that can be easily done by a manager or even a clerical staff. Since it is trial and error though‚ it does not necessarily generate the optimal plan. One downside of this

The purpose of this experiment was to observe the hypothesized correlation between ionic strength and degree of ionization of a weak acid‚ while determining the factors that would impact the degree of ionization using measurements of pH. It was initially required to prepare standard 20-mL solutions of varying concentration of acetic acid for use in the rest of the experiment. One solution of CH3COOH was supposedly developed to be 2.00M‚ however it is highly possible that the solutions of CH3COOH

Calculating correlation values for categorical data In order to find the correlation values for the fields in our data set‚ The Pearson Correlation Coefficient was used. This requires that the data in both fields be quantitative. But what if we were looking to calculate the correlation on two given fields that were say‚ numerical and categorical‚ or even both categorical. The Point Biserial coefficient is a special case of The Pearson Correlation Coefficient; it is a branch of PCC although they
