Answer:

Ratio

Step-by-step explanation:

First lets understand various scales of measurement in psychology

Nominal: Separate numbers indicate separate objects. these no actual meaning other than separating between objects.

example: number on vests of football players

2.Ordinal: meaning order

example: place finished in a race 1st , 2nd

3. Interval: have no order

equal interval between the adjacent categories

the difference between two similar physical quantity is same

4. Ratio: Differences are meaningful like interval

ratios are meaningful , Existence of "true zero point"

Now in the above case money is spend to buy candies which is meaningful and if no money is spent no candies are purchased hence existence of "True zero point"

Hence Ratio scale would be most appropriate to measure this case

Make a ven diagram for a rhombus and a parallelogram

larisa86 [58]

Step-by-step answer:

First we need to know the properties of the given figures.

There are many ways to describe a parallelogram. Here we will use the simple description that

"A parallelogram is a convex quadrilateral with opposite sides equal and parallel."

If we take pencil and paper to construct two parallel and equal lines, and join the corresponding points, we can only get a parallelogram (as long as the figure is convex.

Similarly, if we draw four equal lines to draw a parallelogram, we can only get a rhombus. Therefore a rhombus is a parallelogram with all four sides equal.

See the Venn diagram attached.

Note

(in fact, the minimum definition of a rhombus is "a parallelogram with two adjacent sides equal")
