Think of a correlational study that you might be interested in conducting. Now imagine you’ve conducted it. In a few sentences describe the data you collected, the hypothetical results (including the correlation coefficient), and a concluding statement about the results of your (hypothetical) study.

Expert Solution

I have collected data of such varieties where there are two variables . I won't know is there is any relationship between those 2 variables . So I can apply statistical tool which measure the relationship between those 2 variables which is called as correlation .

But there's is formula for finding correlation coefficient between these 2 variable is given as

r ={xy - mean(x)*mean(y)}/ {sd(x)*sd(y)}

Suppose I get some value of r =c (say)

Where c is lies between -1 to +1

So we can say than accorngly,

If is c is near to 1 there is positive correlation , that is one if one variable is increases the other variable is also increases and vice versa.

If c is very near to zero or equal to zero.then we say that is no relationship between these 2 variables.

If c is near to -1 then we say that there is negative correlation.

That is one variable is increases the other variable is decreases and vice versa .

Imagine that you’ve cloned something that you think is a cadherin, but you know very little about it (and hopefully nobody knows anything about it, otherwise it wouldn’t be “research”). You think it is attached to the cytoskeleton, hypothetically through its cytoplasmic tail. Your goal is to identify the part(s) of the cytoplasmic tail that is/are responsible for binding. Luckily, if you’ve cloned a gene, it is easy to make sub-clones that have specific portions of the polypeptide strand deleted....

Imagine a correlational study that looks at intelligence, the need for cognition, and high school students’ performance in a critical-thinking course. A multiple regression analysis shows that intelligence is not related to performance in the class but that the need for cognition is. Explain what this study has shown in terms of what causes good performance in the critical-thinking course. please write as much as possible with your own words, Thank you.
