(i) The type of scale used in this situation is likely a Likert scale, which is a type of ordinal scale. This is because the responses (e.g. strongly agree, agree, neutral, disagree, strongly disagree) have a clear order but the intervals between each response are not necessarily equal.
(ii) The type of scale used in this situation is a ratio scale. This is because weight is a continuous variable with a true zero point (i.e. someone could have a weight of 0 kg).
(iii) The type of scale used in this situation is an interval scale. This is because the values (ranging from -10 to +10) have a clear order and equal intervals between them but there is no true zero point (i.e. negative emotions do not equate to the absence of emotions).
(iv) The type of scale used in this situation is likely a nominal scale. This is because the test indicates which professions are most suitable for the individual based on their responses, but the professions themselves do not have a numerical value or inherent order.
b) Identify the type of scales of measure used in each of the following situations and justify by mentioning the properties of measurement scales:
(i) As you leave a restaurant, you are asked to answer a few questions regarding what you thought about the service you received.
(ii) When you join a weight loss group, they ask that you keep a dairy book noting your weight each week.
(iii) As part of a research study, you are asked to record your positive and negative emotions ranging from -10 to +10 value.
(iv) When you visit your career services office, they give you a test that indicates professions to which you are best suited.
