Why is the residual sum of squares bigger then total sum of squares when there isn't a constant?
There is a calculation error.
Which statistic estimates the error in a regression solution?
The mean sum of squares due to error: this is the sum of the squares of the differences between the observed values and the predicted values divided by the number of observations.
Is the margin of error always greater than or equal to the standard of error?
Yes
What makes your percent error calculated value not equal to the actual value?
You do not add the percentage error but the actual error.
Is it possible for you to use trial and error method or the X-method to factor the difference of two squares?
No it is not. At least, not sensibly.

What is an anova test?
An ANOVA is an analysis of the variation present in an experiment. It is a test of the hypothesis that the variation in an experiment is no greater than that due to normal variation of individuals' characteristics and error in their measurement.
What is the source of genetic variation that refers to random error in the genetic code?
Mutations
Why does variation occurs when a single cell divides into two cells?
Variation in single celled organisms occurs only when there is a copying error (mutation). The main function of sex is to produce limited variation.
If the two totals of a trial balance are NOT equal it is an indication of a?
error
Is the margin of error always greater than or equal to the standard of error?
Yes
What is the error on 1992 fleer Jeff gardner card number 675?
His position is listed as P (Pitcher), but he was a SS (Shortstop). Beckett Price Guide states that there is a "corrected" variation of this card, but I have not ever seen one. Most error and variation collectors agree that it does not exist.
What makes your percent error calculated value not equal to the actual value?
You do not add the percentage error but the actual error.
Define dynamic error?
dynamic error is caused by time variation in the measured quantity
Sampling error concerns natural variation between samples is always present and can be described using probability Is this true?
No, it is not true. Probability can be used to describe some properties of the variation but not all.

No it is not. At least, not sensibly.
