1) When finding a median, order your numerical list from smallest to larger, as so: 2,2,3,4,5,6,8,9.
2) Then start eliminating numbers from each side of the order; (The bolded numbers will be removed.)
2,2,3,4,5,6,8,9
2,3,4,5,6,8,9
2,3,4,5,6,8
3,4,5,6,8
3,4,5,6
4,5,6
4,5
3) Since there is an even number of digits in your list, you will have to add the last two digits and then divide them by two. 4 and 5 are the last numbers standing, (4+5=9)(9/2=4.5) and therefore your answer, would be 4.5, or B.
Answer:
Explanatory variable: Extra support by faculties
Response variable: whether community college students who have assess into elementary algebra could be successful if they were placed directly into college-level statistics.
Confounding Variable: Ability of students to get passing grades.
It is an experiment to check if the hypothesis is true.
Step-by-step explanation:
An explanatory variable is a type of independent variable. An explanatory variable is that variable that explains changes in another variable. It can be anything that might affect the response variable. The explanatory variable is used to predict or explain differences in the response variable. In an experimental or research study, the explanatory variable is the variable that is manipulated by the researcher.
From the information given,
Explanatory variable: Extra support by faculties.
The response variable is also known as the dependent/outcome variable. Here, its value can be predicted or its variation can be explained by the explanatory variable. In an experimental study, this is the outcome that is measured after manipulation of the explanatory variable
From the question above,
Response variable: whether community college students who have assess into elementary algebra could be successful if they were placed directly into college-level statistics.
A confounding variable is that outside influence that changes the effect of a dependent and independent variable. This extraneous influence is often used to influence the outcome of an experimental design. The Confounding Variable in the above is:
Confounding Variable: Ability of students to get passing grades.
It is an experiment to check if the hypothesis is true.
40 players multiplied by 30 teams = 1,200 players in the MLB
53 players multiplied by 32 teams = 1,696 players in the NFL.
1,696 - 1,200 = 496
There are 496 more players in the NFL then in the MLB.
