Can someone please help me fill in these mulitple choice questions and the last blank? Thank you
When people are anxious, they tend to be depressed. When they are depressed, they tend to be anxious. The relationship between anxiety and depression is well-known to psychologists, but why that relationship exists is not well understood. Does one lead to the other? Are they both part of the same disorder? Suppose you are exploring how measures of anxiety and depression predict future suicide attempts among men over 65. You use the Beck Depression Inventory (BDI) to measure depression and the Beck Anxiety Inventory (BAI) to measure anxiety in a sample of 279 men over 65. Both inventories consist of 21 questions with a possible 3 points per question. Thus, each measure ranges in value from 0 to 63 Which of the following measures or tests would be appropriate to apply to the two numerical scores without any recoding) to ascertain the strength of the relationship between the BDI and the BAI in your sample of men over 65? (Hint: By "recoding" we mean converting data values into ranks, or using the data values to classify participants into categories, such as "not depressed" and "depressed.") O A chi-square test for independence O An analysis of variance (ANOVA) O The Pearson correlation coefficient O An independent-measures t test Suppose you decide to classify the men over 65 into four groups according to their BDI scores. You define those with BDI scores greater than 28 as "severely depressed," those with BDI scores between 20 and 28 as moderately depressed," those with BDI scores between 14 and 19 as "mildly depressed," and those with BDI scores of 13 or less as "minimally depressed." You want to know if the four groups have different levels of anxiety, as evidenced by their mean BAI scores. Which of the following measures or tests would be most appropriate to apply? O A Pearson correlation coefficient O An analysis of variance (ANOVA) O A Spearman correlation coefficient O A chi-square test for independenceExplanation / Answer
1) pearson correlation coefficient
2)an analysis of variance
3)chi square test of independence
