(a)
To explain: The sampling method used in the given study.
The sampling method used in the study is convenience sampling.
Given:
To study the likelihood that a student submits their homework each day, a student observes the number of students who submit homework in each of her classes and the number who do not and gets about 86% of students to submit homework on time and about 5% of them do not submit it on time.
Concept used:
The sampling method where sample data is collected from which is readily available or which is conveniently available is considered convenience sampling.
Explanation:In order to study the likelihood of students submitting their homework on time, a student observes the number of students who submit the homework on each of their classes. This is a convenience sampling method as the student used the data from her class which was readily available.
(b)
To explain: The type of study which was performed to know about the likelihood of students submit their homework on time.
An observational study was performed to study the likelihood of students submit their homework on time.
Concept used:Without altering the subjects just observing and collecting data to analyse the results is considered as an observational study.
Explanation:In order to study the likelihood of students submit their homework on time, a student observes the number of students who submit the homework on each of their classes. This is an observational study conducted to see how many students submit their homework on time.
(c)
To explain: If the statistics can be used to make a general conclusion about all students in her schoolNo, the statistics cannot be used to make a general conclusion about all the students in the school.
In order to study the likelihood of students submit their homework on time, a student observes the number of students who submit the homework on each of their classes. This is a convenience sampling method as student used the data from her class which was readily available. Thus, it is not a true representation of entire students in school, so statistics cannot be used to make a general conclusion about all students in the school.
