What is the type of correlation where there in no relationship between two data sets?
There is no correlation.
What is a line on a scatter plot that helps show the correlation between data sets more clearly?
The answer to ts question is....Trend Line.
A line on a scatter plot that helps show the correlation between data sets more clearly?
A line of best fit or a trend line.
What do you call the relationship between two sets of data?
If the answer you are expecting is correlation, then you are wrong. Correlation refers only to linear relationship between two variables. The correlation for any even relationship over a symmetric domain will be 0. Thus, if y = x2 between the values -a < x < a (for some a), the correlation between y and x will be 0 but few would contend that there is no relationship between the two.
What does no relationship in math mean?
It means that there is no mapping between the two sets of data or between the input and output values. The phrase is often incorrectly used when there is no linear relationship found between two variables, through regression or correlation analysis. Often there can be a non-linear relationship.
What is the type of correlation where there in no relationship between two data sets?
There is no correlation.
What is a line that shows the correlation between two data sets called?
There is no line that shows the correlation between two data sets. The correlation is a variable that ranges between -1 and +1.You may be thinking about regression which, although related, is not the same thing.There is no line that shows the correlation between two data sets.

Do the data sets have a positive a negative or no correlation?

What is a correlation where both sets of data values increase or decrease together?
Positive correlation.Positive correlation.Positive correlation.Positive correlation.
How do you calculate Spearman's rank correlation?
# State the null hypothesis i.e. "There is no relationship between the two sets of data." # Rank both sets of data from the highest to the lowest. Make sure to check for tied ranks. # Subtract the two sets of ranks to get the difference d. # Square the values of d. # Add the squared values of d to get Sigma d2. # Use the formula Rs = 1-(6Sigma d2/n3-n) where n is the number of ranks you have. # If the Rs value... ... is -1, there is a perfect negative correlation. ...falls between -1 and -0.5, there is a strong negative correlation. ...falls between -0.5 and 0, there is a weak negative correlation. ... is 0, there is no correlation ...falls between 0 and 0.5, there is a weak positive correlation. ...falls between 0.5 and 1, there is a strong positive correlation ...is 1, there is a perfect positive correlation between the 2 sets of data. # If the Rs value is 0, state that null hypothesis is accepted. Otherwise, say it is rejected. (sourced from http://www.revision-notes.co.uk/revision/181.html)
