Can u explain 3rd question pls
please add the answers to the report so that we can revise it later. thank you
The answers appear when you click on ‘review quiz’.
i had all correct and I am surprised. well done to myself
OH My l just all the questions wrong
please explain the 5th one john
Suppose the population is 60% women and 40% men, and that we want to question a
sample of 200 total. Decide on a quota of 120 women (60%) and 80 men (40%) and then
stop people as they appear until we have the required number of each.
please explain the 5th one
in the 4th question, it shows quantitative cannot be measured. and it is false. I didn’t mark it but it shows it is true.
how is that possible
you can measure quantitative aspects.
The answer does not show it as true. The answer specifically states that it can be measured.
can you please explain me about the “how the continuous data can take on any value?”
For the 4th question, continuous data can’t be calculated for qualitative information
But that is not relevant to the question as asked.
Is “knowing each item in the population” important in random sampling?
It was helpful ??thank you very much,but please if the answers would be shown after the test it will be nice *
The answers are shown if you click on the ‘review quiz’ button after having submitted your answers!
is “knowing each item in the population” also important in systematic sampling?
No, because we would be selecting every n’th item regardless of what was the case in the population as a whole.
Could you please explain what is population data and what is continuous data?
The population is all the items in the particular category (out of which we take a sample).
Continuous data is explained in the lectures on Measures of average and dispersion.
Could you explain what is the quantitative data?
Question 3
How is the knowledge of each item of the population true of Stratified sampling ?
You have to know what proportion of the population are in each group in order to know what proportion of each group to sample.
What is the mean of the “knowledge is in deeded of each item of population ” about stratified sampling.
Question 2. Why is not multistage sampling, although there is no such answer to choose?
Because taking every 20th item is systematic sampling, not multistage sampling.
See the explanation of both in our free lectures notes and the free lectures that go with the notes.
Now I noticed the tricky moment in the question, it starts just pocking 12th iteam, NOT each 12th iteam.
Thank you for the help, sir
You are welcome 🙂
