Answer 1

Here we are given that,

A professor wants to conduct a study about male soccer players, ages 14-29, who play up to five times per week. Of particular concern is whether or not a player averaged at least 8 headers per game.

Further we are given that,

The psychologist randomly sampled 70 male soccer players, ages 14-29, who played up to five times per week, then recorded whether or not the player averaged at least 8 headers per game.

Now, using above information we have to briefly answer:-

What is the variable? Is the variable qualitative or quantitative?

ANSWER:- Here notice that, the experiment is for the sampled male soccer players in the age group 14-29 of sample size, n=70 who played upto five times per week.

Now, the Variable here is,

X :- the player averaged at least 8 headers per game

Now, the variable X is Qualitative and it can take one of two values, either Yes or No.

i.e. Either a player averaged at least 8 headers per game or not.

Hence, the variable is

X : the player averaged at least 8 headers per game

And the Variable is Qualitative and takes one of two values Yes/No.

This answers your question.
