Answer (end of Chapter 1) questions 5‚ 7‚ 13‚ 17‚ 21‚ 25‚ 27‚ and 31. 5. In an experiment‚ researchers measure two types of variables: independent and dependent variables. (a) Which variable is manipulated to create the groups? Independent variable (b) Which variable is measured in each group? Dependent variable 7. Can a nominal variable be numeric? Explain. Yes. Just as described in the textbook (Page 100)‚ numbers on a nominal scale identify something or someone; they provide no additional information

Comparison of Jack and Ralph Or Lord of the Flies Essay “There is no comparison between that which is lost by not succeeding and that which is lost by not trying” (Francis Bacon). Comparison is a touchy subject‚ one can’t compare directly with someone else because both have had different experiences. Their lives are completely different‚ unless they have both lived through the exact same things‚ then you can’t compare two people evenly without any leniency. Jack and Ralph grow in different ways

that are emitted from an atom in its excited state. A “normal” atom‚ or an atom in its ground state‚ is when all of the atom’s electrons are in their proper energy level. When an atom is in its excited state‚ electrons jump to different energy levels making them unstable. As the electron tries to get back to its respective energy level‚ energy is emitted in the form of light (photons). Every element emits a different color that can be categorized into the bright line spectrum. Different elements

average number of jobs than EDD. Because the SPT rule always results in the lowest average flow time‚ it can result in lower in-process inventories. And because if often provides the lowest average tardiness‚ it can result in better customer service levels. Finally‚ since it always involves a lower average number of jobs at the work center‚ there tends to be less congestion in the work area. What trade-offs should management consider in selecting rules for scheduling the welding machine in the future

Types of Measurement Scales Marc Waters MKT/441 June 9‚ 2014 Cyndie Shadow Types of Measurement Scales Introduction For this week’s assignment‚ students are to select four types of types of measurement increasing order of sophistication; they are Nominal‚ Ordinal‚ Interval‚ and Ratio. These are categories in which numbers are grouped. This paper will also demonstrate how they can be effective in surveys or questionnaires. Nominal The number we assign to some object‚ idea‚ or behavior is

by correlating the concentration of a species in solution to the amount of light it absorbs. It included the observations of absorption or emission of electromagnetic radiation resulting from transitions of atoms or molecules from one energy level to other level. The spectrophotometer measures how much light is absorbed at a given wavelength. When an atom or molecule absorbs energy‚ electrons are promoted from their ground state to an excited state. When a molecule at a ground state absorbs energy

change color while in a flame and with this color‚ I can identify the compound. The test involve putting sample element and see what color appears. Also Thermal excited electron goes from low to high energy level which raises the color but when the excitation ends electron gets to lower level which makes the color back to normal. In order to determine the identity of several unknowns‚ I will perform flame tests and then use my data and observations. Background In this Unit‚ I am studying the

INTRODUCTION In our daily lives‚ we come across news like "prices of goods rising!" or "super discount!". This means that we have to pay a higher or a lower price for the same goods or services. Very often we use index numbers to indicate these changes. In Form 4‚ we have learnt about Index Number from Chapter 11 in Additional Mathematics. Do you know what exactly Index Number is? Well‚ an index number is an economic data figure reflecting price or quantity compared with a standard
