PSY 315 WEEK 4 PROBLEMS

8. Draw conclusions – Assuming that your experiment produced results identical to those seen in Table 4, would you reject or accept the hypothesis that you produced in question 3? Explain how you determined this.

An experiment could be devised in which bats are taken in a large quantity and one

each Ob­Scertainer. I formed a hypothesis for each one, then I took retests to make more

Hypothesis testing and development provides a baseline for taking ideas or theories that were initially created by another person in regards to the markets, economy, or investing and then determining if the

Hypothesis is typically used in quantitative research only. Moreover, when a question poses an inquiry on the relationship between two variables, a hypothesis is a statement declarative in nature of the relationship between different variables (Pajares 2007). A researcher chooses whether to use a question or a hypothesis depending on the purpose of the research, its objectives, the methodology for the research and the preference of the audience to receive the research. A researcher must be able to interpret the final outcome with reference to the research questions or the hypothesis used (Pajares 2007). A research requires a minimum of two hypotheses namely a null and an alternative hypothesis.

Select one (1) project from your working or educational environment that you would use the hypothesis test technique. Next, propose the hypothesis structure (e.g., the null hypothesis, data collection process, confidence interval, test statistics, reject or not reject the decision, etc.) for the business process of the selected project. Provide a rationale for your response.

For the following research questions, create one null hypothesis, one directional research hypothesis, and one non-directional research hypothesis.

2. Choose one of the research questions from above and consider it in more detail. Based upon the question, what would be a reasonable hypothesis?

Cassie and I have conducted an experiment for our Probs and Stats project. We did and experiment to see if listening to music during a test affect your scores. This experiment is relative by most of the students in Alpena High listen to music. As a result of this experiment we were hoping that listening to either classical or rap improves test scores.

f. University of California did a study on children who are given music lessons. The 2nd grade students that were given music lessons scored 27% higher on proportion and fraction tests than those who did not receive lessons.

The first step is to locate and define the problem or desired research issue. The second step is to formulate a hypothesis and decide which method of hypothesis testing should be conducted such as exploratory research, descriptive research, or causal research. The third step is to collect data as primary of secondary such as surveys, observations or rely on other methods such as the census. The forth step is to

5. Conclusion. In the space below, state whether your data supports or refutes your hypothesis. Conclusions are related to the stated problem and hypothesis and supported by data and scientific concepts.

Music defines people. Our generation uses music as a tool to get them through everyday life. Many students listen to music anytime they have a free moment. Sometimes this also means that they listen to music while doing schoolwork. My partner and I performed a study to find out if different genres of music affect 8th grade student's math accuracy. We tested three genres of music. The tested genres were rap, rock, and country. We thought that if we had 8th grade students listen to rock, rap, and country music while doing math tests, then their scores on the tests would increase the most while listening to rock music.

The goal of this lab is to evaluate the effect of different music on test subjects taking math and literature tests, and see which music is the most distracting and the most helpful for subjects. . The objectives of this lab are to observe the effect that the pop, country, rock, and classical music have on the test subjects, and to measure the amount of problem marked wrong against the amount of problems not completed during the task.

Step three: Reach to the result on the basis of test either it can be rejecting or accept the hypothesis.
