IWhat shape does the graph of a linear relationship take?
Linear = Straight line! So, a graph of a linear relationship is a straight line.
What shape does the graph of a linear relationship take?
a line
What shape does the graph of a linear realationship take?
It's linear, so it's a line...
What is Karl pearsons correlation co-efficient?
Pearson's correlation coefficient, also known as the product moment correlation coefficient (PMCC), and denoted by r, is a measure of linear agreement between two random variable. It can take any value from -1 to +1. +1 indicates a perfect positive linear relationship between the two variables, a value of 0 implies no linear relationship whereas a value of -1 shows a perfect negative linear relationship. A low (or 0) correlation does not imply that the variables are unrelated: it simply means a there is no linear relationship: a symmetric relationship will give a very low or zero value for r.The browser which we are compelled to use is not suited for any serious mathematical answer and I suggest that you look up Wikipedia for the formula to calculate r.

What does it means The strength and direction of a linear relationship between two variables?
The direction of a linear relationship is positive when the two variables increase together and decrease together. The direction is negative if an increase in one variable is accompanied by a decrease in the other. The strength of the relationship tells you, in the context of a scatter plot of the two variables, how close the observations are to the line representing the linear relationship. There are various very closely related measures: regression coefficient or product moment correlation coefficient (PMCC) are commonly used. These can take any value between -1 and +1. A value of -1 represents a perfect negative relationship, +1 represents a perfect positive relationship. A value of 0 represents no linear relationship (there may be a non-linear one, though). Values near -1 or +1 are said show a strong linear relationship, values near 0 a weak one. There is no universal rule about when a relation goes from being strong to moderate to none.

What types of hybridization allows for single double and triple bonds and what molecular shapes are formed with each type of bond?
in single bond hybridization will be sp3 and take tetrahedral shape as in CH4 in double bond hybridization will be sp2 and take planar triangle shape as in C2H4in triple bond hybridization will be sp and take linear shape as in C2H2
Illustrate a linear view of a simple feeding relationship?
Well, take a bird's eye view of people having sex.. then show it to your girlfriend, and note her response.
Convert X intervals to z intervals?
The answer depends on the relationship between X and z. This may not be linear, in which case the conversion may need to take account of turning points.
What form does a linear function take?
A linear function when graphed takes the form of a straight line.
How would you find the equation for a linear function when you are given a table of values for the variables?
If the figures in the table are exact and without measurement error then take any two of the points (x1, y1) and (x2, y2) and use these to form the linear relation y - y1 = ((y2 - y1)/(x2 - x1))(x - x1) If, however, you suspect that the values in the table do not exactly follow a linear relationship then use linear regression for which formulae are provided in wikipedia.
What kind of research is needed to identify relationships between variables but does not determine cause and effect?
Correlation. It will merely determine whether or not there is a linear relationship between the variables. However, the absence of correlation is not absence of a relation - only that the relationship is not linear.For example, if you take any set of points that are symmetrically placed about a vertical axis - such as from a circle, ellipse or parabola, or parts of a sine or cosine curve - then the correlation will be 0. But, the fact that these are well-defined curves clearly implies a very definite [non-linear] relationship.
