What is the level of measurement for each of the following variables? a. Distance students travel to class b. A classification o

Lunna [17]

Answer/Explanation:

There are basically 4 main levels of measurement or scales of measurement. They are:

1. Nominal scale: this deals with variables that are categorised, and numbers o i.e.r alphabets assigned are just for the sake of naming, and as such has no numeric value.

2. Ordinal scale: this scale is only used to show order or ranking if variables.

3. Interval scale: in this type of scale, numbers that are ordered have meaningful divisions.

4. Ratio scale: this can be like to interval scale, in that, the ordered numbers have meanings. However, unlike the interval scale, when zero is used, meaningful deductions can be made as zero is meaningful.

Therefore, level of measurement for the variables given in the question are as follows:

a. Distance students travel to class: ratio scale. I.e. zero in this scale is meaningful and would mean no distance was travelled

b. A classification of students by the state of birth: nominal scale, i.e. this only serves the purpose of categorization. The scale here has no numeric value,

c. A classification of students by ethnicity: nominal scale

d. A classification of workers by industry: nominal scale

e. Selling price of the Statistics textbook: ratio scale

f. Student IQ ratings: interval scale, i.e., zero in this scale is not meaningful.

Jessica and Raphael are saving money for concert tickets. Jessica has $20 and saves 10 per week.

Burka [1]

They have the same amount on week 5 ($70)
The Answer would be: $70
((Got this correct on my quiz, If you need it explained, It is below))
The easiest way to do this is to not pay attention to the y=x equation, because the solution is already in the information, this may confuse you and youre wasting time to solve it. Jess has $20 BEFORE saving and gets $10 WEEKLY, Raph has $40 BEFORE saving and gets $6 WEEKLY. In the chart/information, add the amount it takes to get Jess up to $40 then add $10 for every week on going until both their balances are equal. They match on the 5th week with $70 // If the information is different substitute the names/numbers/etc. Hope this helped you and anyone else looking for the answer!

Which ordered pair is the on the graph of the equation 2x+5y=4?

romanna [79]

To investigate which of the choices satisfy the equation, substitute the values of the abscissas into the equation and solve for y. See if the value of y calculated is equal to the value of the ordinate of the point.

A. (7, -2) ; (2)(7) + 5y = 4 ; y = -2 EQUAL

B. (0, -1) ; (2)(0) + 5y = 4 ; y = 0.8 NOT EQUAL

C. (0, 1) ; (2)(0) + 5y = 4 ; y = 0.8 NOT EQUAL

D. (3, -2) ; (2)(3) + 5y = 4 ; y = -0.4 NOT EQUAL

Thus, the answer is letter A.
