Answer:
The correlation is more valuable. It can be used to determine the relative strength of a linear relationship.
Explanation:
When you talk about finding a relationship between two quantitative variables such as calories and sugar, then the best that can be used in expressing this relationship is correlation. Correlational research is very useful because it helps in discovering the strength and directions that exist in a relationship between two variables. Although it does not say much about the cause and effect, it is used as a measure of linear relationship between two variables.
Covariance can mainly show the direction between two variables, but cannot be employed when trying to calculate the strength of the relationship between the variables. Correlation coefficient does a better job in measuring the strength of relationships between two quantitative variables.
Answer:
c)
Explanation:
A type II error refers to the non-rejection of a false null hypothesis (also known as a "false negative" finding or conclusion). This means that the null hypothesis is false and you fail to reject it .
The type II error gives you a false negative conclusion, meaning that it tells you something is false when it's actually true.
Observing the option we have we can conclude that the one that refers to type II error is c) Concluding that a treatment has no effect when it really does (false negative)
<u>Note; </u>
<u>A) and B) show no errors.</u>
<u>D) shows a Type I error where you conclude something is positive when it's actually false. </u>
Reflective practice : studying your own experience to improve the way you work.
for example :
- When i work as an accountant for a beverage company for about 3 years now. Believe it or not, i do more works in this past 6 months than i ever did during the previous 2.5 years.
When i first started this job, i basically do everything at once. I always activate 3 or 4 laptops in my desk because i think it will make me more productive. But i was wrong.I made a lot of mistakes and my jobs become unorganized since doing multitasking robbed me from my focus.
After i tried focussing myself to do 1 particular task of the time, my work results became a lot better and i'm able to do more tasks a lot faster
