2. Give an original example of an experiment with at least two conditions and high external...
1.Explain case-control and cohort study designs? How do the two designs differ? Give at least one example from the text or the literature. 2. Define validity and reliability using examples.
Please give an example or situation that has high idle time and offer at least two ways to decrease it, thereby increasing profitability.
10A) Give an example of a paired data set (with at least 5 pairs) that demonstrates a strong (but not perfect) negative linear correlation. x y 10B) Give a real life example of two variables that are likely to be positively correlated. Specifically explain why you believe your chosen two variables are positively correlated. 10C) Suppose some researchers studied children in high schools and found a strong positive linear correlation between the availability of vending machines and obesity. From this...
Solve 1.Define reactivity as it relates to a scientific experiment. Provide two specific examples of how reactivity might affect a naturalistic observation experiment. 2.Explain the difference between a non-experimental method and an experimental method. Include a description of how each method is performed and identify which type of validity is more associated with each one. 3.Define both qualitative data and quantitative data. Then, identify the purpose, the group who is studied, and the role of the researcher for each type...
5. Explain the difference between a Nash equilibrium and a dominant strategies equilibrium. Give an example to show how the prisoners' dilemma helps to explain behaviour. 6. Why might a firm set prices based on a markup above average cost rather than equalising marginal costs and marginal benefits? 7. Using a diagram, explain how an external cost of production (i.e. a negative production externality) can be internalised with a tax. |8. Explain the conditions of price discrimination. Give two examples...
In the following two paragraphs, fill in the blanks using the pumbers corresponding to the words or word phrases below. Note that each word or word phrase may be used more than once, but that not all words will be used (worth 1 point per blank) 1. internal validity 2. extraneous 3. equivalence confounding extraneous variables 5. manipulated causal validity population validity selectively 9. non randomly 10. correlational 11. real world 12. external validity 13. randomly 14. nonequivalence 15. independent...
For each of these conditions— deadlock, race, and starvation—give at least two “real life” examples (not related to a computer system environment) of each of these concepts. Then give your own opinion on how each of these six conditions can be resolved.
What is exception propagation? Give an example of a class that contains at least two methods, in which one method calls another. Ensure that the subordinate method will call a predefined Java method that can throw a checked exception. The subordinate method should not catch the exception. Explain how exception propagation will occur in your example.
4. a) Draw an example of two non congruent triangles that satisfy the following conditions. If not possible, explain why. (1) The two triangles have congruent corresponding angles. (ul) The two triangles have congruent corresponding angles, and one pair of sides (not corresponding sides) congruent. () The two triangles have congruent corresponding angles, and two pairs of sides (not corresponding sides) congruent. b) (i) is the statement "If A ABC A DEF, then 2CAB ELFED", true or false? Clearly explain...
Covalent solids can be low or high melting. Give an example of each and explain why each one is so.
