Answer:
The researcher should use correlation analysis for his studies.
Step-by-step explanation:
What is correlation?
Correlation is a statistical tool used to quantify the degree to which two variables are related. Through the correlation analysis, you evaluate correlation coefficient that tells you how much one variable changes when the other one does. Correlation analysis provides you with a linear relationship between two.
Types of correlation
1. Positive, Negative or Zero Correlation:
2. Linear or Curvilinear Correlation:
3. Scatter Diagram Method:
4. Pearson's Product Moment
Coefficient of Correlation:
5. Spearman's Rank Correlation
Coefficient:
Answer:
there are 34 green marbles
there are 91 total marbles
Step-by-step explanation:
57 - 23 = 34
57 + 34 = 91
Answer:
(10x25) + (5x25)=375
Step-by-step explanation:
Ten times any number is easy because you just add a zero to the end. So mental math would say to break it into 10x25=250, plus 5x25=125, which equals 375
Answer:
Step-by-step explanation:
Let the both the parts be 'x' and 'y'
x>y
We know that 4x = 5y
so x = 5y/4
x + y = 54
Replacing x we get
(5y/4) + y = 54
(5y +4y)/4 = 54
9y = 216
y = 24
Replacing y in ' x+y = 54'
we get x = 30
Hence the larger part is 30 whereas the smaller part is 24
