What was the researcher hypothesis for negative correlation of blue jays and golden-cheeked?
The researcher hypothesized that a negative correlation between blue jays and golden-cheeked warblers could be attributed to competition for resources, such as food and nesting sites. Blue jays, being larger and more aggressive, may outcompete golden-cheeked warblers, leading to decreased populations of the latter in areas where blue jays are prevalent. Additionally, the presence of blue jays could increase predation risk for the more vulnerable golden-cheeked warblers, further contributing to their decline in such habitats.
What else can I help you with?
What value or benefit would a researcher gain by calculating a correlation coeffcient rather than simply describing the relationship as a positive correlation or a negative correlation?
The correlation coefficient gives a measure of the degree to which changes in the variables are related. However, the relationship need not be causal.
What is the difference between positve and negative correlation?
Positive correlation has a positive slope and negative correlation has a negative slope.
What does the sign of the correlation coefficient tell you about the association?
Positive correlation = positive association Negative correlation = negative association
Are negative correlation and reverse correlation same?
No.
What are three types of correlations?
positive correlation-negative correlation and no correlation
Correlation coefficient is the measure of?
Correlation coefficient is a measure of the strength and direction of a relationship between two variables. It quantifies how closely the two variables are related and ranges from -1 (perfect negative correlation) to 1 (perfect positive correlation), with 0 indicating no correlation.
Is -.187 a positive or negative correlation?
It's a negative correlation because it is less than 0
What negative correlation indicate?
the negative sign on correlation just means that the slope of the Least Squares Regression Line is negative.
Is certain a negative connotation or positive correlation?
A positive correlation.
Is 0.5 the strongest correlation coefficient?
No. The strongest correlation coefficient is +1 (positive correlation) and -1 (negative correlation).
What are the trends of a line?
They can be positive correlation, negative correlation or no correlation depending on 'line of best fit'
What is a negative correlation?
A negative correlation is a measure of the linear component of a relationship where one variable increase as the other decrease.
