A study is designed to examine levels of knowledge regarding insulin administration. the researchers want to see if a person age effects their findings. therefore, they ask participants to mark a category regarding their age. the categories are as follows.

less than 18 years

18-29 years

30-50 years

50-65 years

greater than 65 years

what type of data is this for the age category

a) nominal

b) interval

c)ordinal

d) ratio

Expert Solution

The type of data is this for the age category - option c Ordinal

Because Ordinal data is qualitative data and not based on numbers , exact difference but mainly calculated by mode or median method.In this case age groups are not with exact difference in numbers and not providing exact value between age groups

Other options are incorrect as option a Nominal is basically called as name as it is qualitative and not quantity based which don't have numbers in it and such data has names or labels for example colour of a dresses can be blue , black , red .So options and choices are labelled or named and not numerical unlike this question

Option b is also incorrect as Interval provide quantitative data by giving exact difference in values such as difference of 10 between 10 - 20 and 30 - 40 but in this case exact value and difference can't be determined.

Option d is also incorrect which is ratio as Ratio called as outmost which provide order , exact difference and exact value and it also have an absolute zero which is not in this case.

Thus the correct option is C - Ordinal type

PLEASE UPVOTE IF YOU FIND IT SATISFACTORY.COMMENT IF ANY DOUBT.

In a study to examine the effects of homeopathic treatment of wounds, researchers sutured a deep muscular incision on anesthetized rats and randomly assigned rats to 5 treatments: a placebo (sugar water), two homeopathic remedies (Arnica and Staphisagria) each administered at two levels of dilution. The treatments were consumed daily by the rats, and the time it took (in days) til healing was complete was measured for each (see columns healing time and treatment in your HW5b spreadsheet). Is there...
