Question

which of the following would be considered a very strong negative correlation?
a) 0.89
b) -0.09
c) -0.89
d) 0.09​

Answer 1

Answer:

(A) 0.89

Explanation:

The value of a strong negative correlation is to show as one variable increases, another variable reliably decreases

Examples

• the number of mistakes made on simple tasks increases as average hours of sleep per night decreases
• As time playing catch increases, the number of dropped balls decrease
• The average daily temperature of the United States and Australia (Summer in North America is winter in Australia)
• Time spent practicing a musical piece and the number of errors made. The more a musical score is rehearsed, the more accurately it is played.
• Hours of sleep and traffic accidents. Fatigued people make more driving mistakes.
• Items placed on sale sell more of that item. Price is negatively correlated to sales.
• Each of these is a negative correlation because they share an inverse relationship.

Answer 2

Answer:

(A) 0.89

Explanation:

(A) 0.89

Strong negative correlations are valuable because they demonstrate that while one measure rises, another variable consistently falls.

Examples

less hours of sleep per night result in more blunders being made on easy activities.

The quantity of lost balls decreases as playing time at catch rises.

Australian and American daily temperatures on average (Summer in North America is winter in Australia)

The amount of time spent honing a musical work and how many mistakes were made. A musical score may be played more properly the more it is practised.

sleep duration and traffic incidents. People who are tired while driving make more errors.

Sales of an item increase when it is discounted. Sales and price have a negative relationship.

Each of these is a negative correlation because they share an inverse relationship.
