Reliability Statistics Cronbach's Alpha Erased on Standardlznd Cronbach's Alpha Items 1. Based on the table above, report the reliability . Is this a strong, moderate, or weak reliability? Validity Determine which validity is best described in the following scenarios 1. There is no objective, observable entity called \"depression\" that we can measure directly. But based on existing psychological research and theory, we can measure depression based on a collection of symptoms and indicators, such as low self-condence and low energy levels. What type of validity does this infer? 2. An epidemiology teacher develops an end-ofsemester test for her class. The test should cover all of the basic epidemiological concepts that was taught in the class. What type of validity should this test be sure to have? 3. You create a survey to measure the regularity of people's dietary habits. You review the survey items, which ask questions about every meal of the day and snacks eaten in between for every day of the week. On its surface, the survey scents like a good representation of what you want to test. What type of validity is this? 4. A university professor creates a new test to measure applicants\" English writing ability. To assess how well the test really does measure students' writing ability, she nds an existing test that is considered a valid measurement of English writing ability, and compares the results when the same group of students take both tests. If the outcomes are very similar, then her new test shows what type of validity?

Hypothesis Testing - Complete the Hypothesis Test Below on the following page: A researcher wanted to study the effects of mentoring on emotional intelligence of at-risk teens. He used a standardized test which has a mean of 100 and standard deviation of 16. The 50 students in his study scored an average of 102 on the IQ test. Are the mentored students reflective of the normal population? Test the hypothesis using a .05 alpha. Steps Your answer 1. State your null hypothesis (in words) 2. State your alternative hypothesis (in words) 3. Record your alpha level. 4a. x-bar is the 4b. x-bar = 4c. Mu is the 4d. Mu = 4e. Sigma is the 4f. Sigma = 4g. n is the 4h. n= 5. Work out the equation and write in the z- score obtained. (formula pasted below the table) 6. Use your cursor to move the blue dot to where the z-score falls on the normal curve (below the table). . 7. Are the mentored students reflective of the normal population? 8. Will you accept or reject the null hypothesis? Hint: if they are reflective of the normal population, you should accept; if they are not reflective of the normal population, you should reject. x - Ul Z = File Home Insert Design In 16 Cut Calibri (Body * 1 Copy Paste Format Painter BIU - abe Clipboard
