Evaluate the statistical analysis packages available for quantitative research. Which statistical analysis packages would be most beneficial for the examination of quantitative data within your study? The four most common statistical packages that nurses use for research are Statistical packages for the Social Sciences (SPSS)‚ Microsoft Excel‚ XLSTAT‚ STATA and SAS (CourseConnect‚ 2016). For my research study‚ I would use the SPSS package because it is easy to use‚ can take data from almost any

Copper was the first metal that is used by humans as weapons and tools. It is shinny and has a reddish brown color. It’s application toward humans has really changed the way we live. Copper is an excellent conductor of electricity‚ which is often used as electrical wires or cables in generators‚ motors and electric products. In addition‚ it is also an outstanding conductor of heat‚ which is used in radiators and heating systems. Since it does not react with water and corrode easily‚ it is widely

The Effect of pH Level of a Liquid on the Rate of Corrosion of Copper wire In this experiment‚ I will be testing the corrosion rate of copper wire after leaving them in different liquids with different pH levels. By doing so I will be able to determine which pH level corrodes copper the fastest. I will conduct this experiment by pouring 250mL of different liquids with different pH levels in cups‚ followed by an iron strip placed into the cup. A stopwatch will be timing how long it takes the iron

A Sequence of Chemical Reactions: Transforming Copper Briefly describe. a) Why must you carry out the oxidation of Cu with HNO3 in a fume hood? Concentrated nitric acid is a toxic oxidant. Avoiding skin contact or inhalation is highly important. The reaction between Cu and HNO3 produces NO2‚ a toxic brown gas; therefore working under the fume is necessary in order to prevent inhaling the toxic gas. b) Why you should be particularly careful when you work with 3 M H2SO4 solution? Sulfuric acid

Coursework 4 Copper Name of student: Alfiya Ospanova Tutorial group: G Copper is one of the earliest elements explored by humanity. Due to the special red shade it was easy to find in ancient times. The metal was named according to place where it was found‚ the Cyprus islands. Copper produced in massive stars and spread in the world as minerals like chalcocite and chalcopyrite (sulfide of copper)‚ azurite and malachite (carbonate of copper)‚ cuprite (oxide of copper).

Research question/Aim Extract copper from copper oxide by reduction using butane gas Hypothesis The butane gas will reduce the copper oxide and leave behind pure copper. This will allow us to find the empirical formula of the copper oxide as well as the masses of oxygen and copper Variables Dependant variable The dependant variable will be the reduction of the copper oxide which will be calculated at different temperatures. Independent variable The independent variable here

BASIC QUANTITATIVE ANALYSIS FOR MARKETING BASIC TERMINOLOGY Simple calculations often help in making quality marketing decisions. If we are to assess the likely profit consequences of alternative actions‚ we must understand the cost associated with doing business as well. We can calculate the expected revenue generated by each pricing strategy‚ but without cost information‚ it is not possible to determine the preferred price. The cost concepts we introduce are: - Variable cost - Fixed cost
