A study was conducted to compare the effects of three different drugs on the alleviation of anxious depression in non-psychotic patients. Twelve non-psychotic patients, all suffering from moderate to severe depression and anxiety, were grouped according to initial level of severity. Patients in each severity level group were randomly assigned to the three treatments (drugs). At the end of the experimental period, a combined anxiety and depression score as determined by the MMPI and Taylor Manifest Anxiety Scale was recorded...
identify the dependent variable (and how it is measured – also include categories if nominal or ordinal), independent variable (and how it is measured – alsoinclude categories if nominal or ordinal), and what statistical test you would use to answer the question.[NOTE:You need to report a DV and IVvariable name -- be sure not to just report categories as the DV or IV variable name – points will be taken off for that mistake.]Also, for the Factorialand Mixed-Design ANOVAs you...
Write a research question for each of the following phenomenon. Make sure you have an Independent variable and a Dependent variable identified for each statement, by indicating (IV) and (DV) behind the appropriate term. Remember that the DV is the outcome being measured, and that it is dependent upon the IV, which is the intervention. (For example: anxiety level of hospitalized children and parent rooming in. My research question is: Is the anxiety level (DV) of hospitalized children decreased when...
In a follow-up to Sperling (1960), researchers were interested in whether a tine delay affected the span of apprehension of adolescents To test this, they conducted a study where participants were recruited to complete a span of apprehension task where they viewed a display of letters and, after the letters disappeared, vere asked to report a subset. All participants were presented with each of two conditions. In the no delay condition, after the letter display was removed, participants were...

1. Identify the formula for predicting an individual's z score on the dependent variable from their z score on the independent variable. a.) (rxy)(zy) b.) (rxy)(zx) c.) zx/zy d.) (zx)(zy) 2. Data from the 1993 World Almanac and Book of Facts were used to predict the life expectancy for men in a country from the life expectancy of women in that country. The resulting regression equation was Yˆ = 9.32 + 0.79(X). Using the regression equation, what would you predict...

Consider a multiple regression model of the dependent variable y on independent variables x1, X2, X3, and x4: Using data with n 60 observations for each of the variables, a student obtains the following estimated regression equation for the model given: y0.35 0.58x1 + 0.45x2-0.25x3 - 0.10x4 He would like to conduct significance tests for a multiple regression relationship. He uses the F test to determine whether a significant relationship exists between the dependent variable and He uses the t...
