Here are 6 short answer questions need to be answered individually by following the instructions listed underneath each of them. They all belong to the Research

Methods. Just remember not to go beyond the word limit mentioned and to mention the reference underneath each of them. My deadline to receive them from you is Sunday

night, 8th. of December 2013, UK timing.

Question no. 1

A colleague is constructing a questionnaire to be used with individuals with chronic respiratory disease, seeking information on their utilization of health care and

their satisfaction with local primary care services. She has produced a draft of her questionnaire but is unsure about the sequencing of questionnaire items. In no

more than 200 words, give a reasoned account of one piece of advice you would give on the appropriate sequencing of items in her questionnaire.

Question no. 2

In relation to ethnographic research, explain in up to 250 words one advantage and one disadvantage of a researcher immersing him- or herself in the social environment

that is the object of the study.

Question no. 3

You read in a paper that a sample of patients have a mean score of 23 on a 0?100 health status scale, with a standard deviation of 42. What can you infer from this

information about the distribution of health status scores in this sample?

Question no. 4

A research team are interested in the possible causative role of prolonged use of an antispasmodic drug A in the development of a particular neurological symptom. They

identify from current attenders at a neurology clinic a group of patients who have experienced this symptom within the last four weeks and a group who have not

experienced it within this same period. They then search the medical records of all these patients to determine prior use of drug A. In this way, they will seek to

test for an association between drug A and the neurological symptom.

a- What type of study design does this description represent?
b- Describe and explain, in up to 150 words, one potential methodological problem in this study.

Question 5

If the size of a random sample from a normally distributed population is increased, which of the following would you expect to be affected and in what way(s)? Provide

not more than one sentence in relation to each.

1. The mean value of the scores
2. The standard deviation of the scores
3. The standard error of the scores
4. The shape of the distribution of the scores
5. The level of measurement of the data

Question 6

In a randomized controlled trial, participants are allocated to treatment groups via a chance process known as randomization. The variable that defines the treatment

groups is known as the ………[1]. If the process of randomization is designed so as to create treatment groups of equal size, this is referred to as ……… [2]

randomization. If it is particularly important that certain key variables are balanced (equalized) across treatment groups, this may be accomplished by means of

……… [3] randomization. Sometimes, rather than allocate participants through randomization, an algorithm is set up whereby the first participant is allocated

randomly, but each subsequent participant is allocated so as to minimize the differences between the groups in respect of certain prognostic variables; this process is

known as ……… [4]. When the trial data are analysed, the researcher may choose to analyse each participant in terms of the group to which he or she was allocated

regardless of whether or not the participant actually received the allocated treatment for that group; this type of analysis is known as ……… [5].
