Operationalize the dependent variable in the following hypothesis statement as a ratio-level measure, “It is hypothesized that people who complete annual physical exams (compared to those who do not complete annual physical exams) will be healthy.”
Homework Answers
The hypothesis: "People who complete annual physical exams (compared to those who do not complete annual physical exams) will be healthy."
Here the dependent variable is periodic Diagnosis of health-related problems & treatment of these conditions accordingly. In annual physical exams, the history of the patient's health is taken into account & also his vital signs like blood pressure, heart rate, BMR, temperature are measured , along with a thorough check-up on the heart & the lungs. If there is a condition, it can be easily detected in its early stage due to periodic & regular diagnosis, and preventive measures can be taken which are more effective than curative measures (which are taken once the disease has fully set in).

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...

A colorful frog species has four color morphs. It's been hypothesized that frequency-dependent selection will stabilize the color morphs in a population to a 1:1:1:1 ratio. You collect 160 frogs and observe the following numbers: red spot 34 yellow 48 blue stripe 40 pink chevron 38 The question of interest is whether the frogs in this population are in a 1:1:1:1 ratio. Step 2: State the null hypothesis. Step 3: State the alternative hypothesis. Step 4: What is the correct...

In controlled comparison research, the observed relationship between an independent variable (X) and a dependent variable (Y) may be caused by some other, uncontrolled compositional difference (Z). So, we always ask, “How else, besides the independent variable, are the groups I am comparing not the same?” For the hypothesis below, do the following: (i) Think up a plausible alternative causal variable. (ii) Describe how this variable might affect the relationship between the independent variable and the dependent variable. In a...
