Basic Stats for psychology
babymother [125]

Answer:

Ratio

Step-by-step explanation:

First lets understand various scales of measurement in psychology

  1. 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

ale4655 [162]

Answer:

Unit rate is 32.9561 feet per second.

Unit rate is a number where one quantity is represented so that the other quantity is 1.

So we can give the unit rate of this as number of feet per 1 second.

It has traveled 692.08 ft in 21.1 seconds.

We have to find how many feet it travels in 1 second.

Unit rate = Number of feet / Number of seconds

=\frac{692.08feet}{21.1seconds}

=32.9561 feet per second
