What is the difference between biserial and point biserial coefficient?

Dichotomous variables can be either a discrete/true dichotomy or a continuous/artificial one. Examples of discrete dichotomies are male vs female, dead vs alive. There is no underlying continuum between the groups. Continuous or artificial dichotomies are those which we assume there to be an underlying continuum but we assign individuals to a category based on some arbitrary criterion. Examples of this artificial dichotomy are pass vs fail (based on some cutoff score on a test) or short vs tall (based on some arbitrary height). A point-biserial and biserial correlation is used to correlate a dichotomy with an interval scaled variable. The difference is that the point-biserial correlation is used when the dichotomous variable is a true or discrete dichotomy and the biserial correlation is used with an artificial dichotomy.

How do you find the other endpoint of the line segment with the given endpoint and midpoint?
Add the same amount again by finding the difference of the midpoint and end point. Example: If the end point is 3 and the mid point is 9. The difference between 3 and 9 is 6 so add 6 to 9 and get 15.
What is difference between 1 percent increase and 100 basis point increase?
The difference between these increases is that 1% increase gives the 101% increase of the original amount of points while 100% basis increase gives the 200% increase of the original amount of points.
What is the difference between the slope and the y-intercept?
The slope is the value of m in which you "rise and run" point units The Y-intercept is the value in which X is zero
What is the difference between differences and similareties?
A difference is a point or way in which people or things are not the same, while a similarity is the state or fact of being similar.Differences are the discrepancies or the unlikeliness between objects. This can be also referred as the contradictions from one another.Similarities are the likelihood of one another.For example a difference would be:A tiger has stripes and a cheetah has spots.A similarity would be:A tiger and a cheetah are both big cats.
What is the difference between mesh analysis and nodal analysis?
In Mesh analysis you are using the values of the currents within a certain part of a circuit. In Node Analysis, you are observing the voltage at a certain point.
