"Patients with type 2 diabetes who receive instruction on an individual basis will be more compliant than those who receive instruction in a group setting." Identify the dependent variable in this hypothesis. compliance type of instruction type 2 diabetes individual versus group setting

A

A research hypothesis always: predicts a relationship. asks a question. none of the responses are correct. is based on expert opinion rather than prior research data.

A

An example of a directional hypothesis is: Persons with dementia who receive an orienting intervention will show less confusion and fewer problem behaviors than those who do not receive the orienting intervention. There will be no difference in maternal and infant outcomes between women giving birth in a hospital and those giving birth at home while cared for by a midwife. Patients with a hydrocolloid dressing and those with a standard gauze dressing will show differences in the incidence of catheter-related infection and local inflammation at the insertion site of those receiving total parenteral nutrition (TPN). There will be a difference in weight among persons who have attended a nutrition program compared with those who have not attended such a program.

A

Identify the independent variable in the following hypothesis: "Adults in an overweight group will have lower health responsibility scores compared to those in a normal weight group." overweight group versus normal weight group health responsibility none of the responses are correct. adults

A

Which of the following statement is in the form of a null hypothesis? There is no difference between males and females on the variable quality of life. There is a correlation between smoking and lung function. The child has a learning disability. There is a positive relationship between grades and time spent studying.

A

Hypotheses can be classified as: simple or complex. all of the responses are correct. nondirectional versus directional. research versus statistical.

B

Identify the dependent variable in the following hypothesis: "Exercisers exhibit higher self-efficacy scores compared to nonexercises." none of the responses are correct. self-efficacy nonexercisers exercisers

B

Control techniques are introduced to reduce the contaminating effects of: independent variables. null hypotheses. extraneous variables. dependent variables.

C

Hypotheses that do not specify a particular direction in relation to variables under study are called: null hypotheses. extraneous hypotheses. directional hypotheses. nondirectional hypotheses.

D

You are concerned that subjects presenting to the emergency room with nonemergency problems are not following through on recommended referrals. You believe that you can influence compliance by incorporating systematic patient teaching into the visit, so you design a teaching intervention. Persons who present to the emergency room with a urinary tract infection are randomly assigned to receive or not receive the teaching intervention; those not receiving the intervention are given a short written handout containing instructions to follow through on referral. The independent variable is: follow-through on referral. emergency room. urinary tract infections. teaching intervention
