Ch.1. Review Amber Hennrich May 26, 2014 12. Explain and give an example for each of the following types of variables: (a) equal-interval, (b) rank-order, (c) nominal, (d) ratio scale, (e) continuous. A) An equal-interval is a variable in which numbers stand for approximately equals amounts of what is being measured. Example: Grade Point Average B) A rank-order variable is numeric and the numbers stand only for the relative ranking. Example: A graduate standing in their class. Their GPA

Week 4 Individual Assignment Erwin O. Raymer III PSY/315 Jan. 13th 2014 Jennifer Lapin Week 4 Individual Assignment The five steps of hypothesis testing consist of the following. Restate the question as a research hypothesis and a null hypothesis. This is where an individual would make a research hypothesis, which is basically a prediction intended to be tested in a research study. This prediction is usually based on the researcher’s theory. A null hypothesis

PSY/315 March 18, 2013 Chapter 7 14.) Evolutionary theory often emphasizes that human have adapted to their physical environment. One such theory hypothesizes that people should spontaneously follow a 24-hour cycle of sleeping and waking-even though they are not exposed to the usual pattern of sunlight. To test this notion, eight paid volunteers were placed (individually) in a room in which there were no light from outside and no clocks or other indications of time. They could turn the lights

Madame President Herrera, Now that you have learned how the Justices can influence the decision-making process and have learned how the nomination process essentially works, we now want to turn to an area that she will want to be weary of when choosing two particular nominees. We call this area that you want to watch out for “red flags.” There are many different red flags that can indicate a potential nominee is going to not be the right choice. First, as the president she will want to check

Question 3 a) Although all the ratings are measured based on the same scale (thus, same unit), the scores of the variables have various means and standard deviations, indicating that the rating of each variable distributes differently from one another on the scale. Standardizing the data makes the means of the variables equal to zero and standard deviations to one. The standardization realizes the subsequent analysis of the correlation matrix and makes it easier to interpret the principal components

Based on the experiment illustrated in the picture and the experiment that I conducted, I concluded to the following results. The probability of getting a possible 3 if we roll one die, is 1/6 as the die has 6 sides and the number 3 is only in 1 side of the die. Although, if we roll two dice, the probability of getting a possible 3 in at least one die, is twice as likely to occur with a chance of 1/6 in the one die plus 1/6 on the other, which is equal to 2/6 for both dice and therefore simplified

As we begin this project we start with simply placing the four pedals in the correct order onto the pedal board. The placements of these pedals are critical. If we place them in the wrong spot the pedals will not have their full sound potential. The first pedal that must be placed is the Noise Reduction pedal. This pedal muffles unwanted feedback and humming that would initially come from our amp when we have the sound cranked up for live performances. The pedal placement for this pedal is very important

Problems 1-10 were each worth one point, since question 9 had two parts, students could receive a total of 11 points for questions 1-10. Question 11, was worth a total of three points. Students would receive a point for each, if they were able to use the equation (15/3) to make three groups, place one manipulative at a time into each group until reaching 15, and counting the tiles to receive the answer (5). Therefore, students had an opportunity to receive 14 total points for the test. The problems
