A correlation analysis between the heart rate and timing. the result is 0.9327?

Question

A)DISCUSS THE RESULT.
B)CAN THE CORRELATION BE VALID.COMMENT ON THIS.
C)ASSUMING THE CORRELATION IS VALID SUGGEST SOME WAY OF HOW THE RESULTS CAN BE USED.

Answer 1

a) Since the result is positive and not negative, there is a positive relationship between the two variables. This means that as one variable increases, the other one does as well. If the result were negative, say -0.9327, you would have an inverse relationship where one variable would decrease in value as the other one increased, and visa versa. The number 0.9327 can be rewritten as 93.27% by moving the decimal two places to the left. Now this number is easier to interpret; it looks like there is a VERY strong positive relationshp between the two variables. As one variable increases, the other will increase 93.27% of the time. If your result were closer to 0.5, you would say there is a moderate positive relationship, and numbers closer to 0.1 and smaller have weak relationships, if any.

b) I don't know if this correlation is valid. There are two main types of validity with most experiments: external and internal validity. How it was the experiment conducted, where all factors accounted for?

c) Assuming there is a high degree of internal validity, you can interpret the results as there being a strong positive correlation between heart rate and timing. I would be able to help you further but I honestly don't know what you meant by "timing". Do you mean "timing" as in a race, or in heart beats per minute, etc?

Hope this helps

Answer 2

What is timing? The measurement of interval between heart beats?
In any case, a correlation of .9327 is a high correlation, and it means that heartbeat is directly related to timing, or that timing is a good way to measure or specify heart rate,

Answer 3

A) thgey are higly correlated meaning that changes in one results in a predictable changes in th second.
B) it could be valid since we have no id3ea whaty the timing is
C) the usgage coul be to make a precision watch that runs on the heartbeat. or an automatic hospital-dialer for people with cardiac problems who have lost their fingers
