What does a double bracket mean in math? What information do we need to calculate r-squared? a. r b. r, and a and b c. r, mean of X, and mean of Y d. r and b Compute double intgral R d x d y ( 4 x + 5 y + 3 ) 2 where R = (1,2) * (0,1). ...
The variance of a discrete random variable X is a weighted average of the squared deviations of the possible values of X from the mean, using the probability of each X value as weights: (4.9)σ2=E[(X−μ)2]=∑(Xi−μ)2P[Xi] The Greek symbol σ is pronounced “sigma.” The ...

What does the effect size ( η^2) in an ANOVA tell us? a. How much of the total variance is within-groups variance. b. How much of the total variance is between-groups variance. c. The magnitude of the total variance. d. How far apart the means How is the mean squared deviat...
Population variance (σ2) tells us how data points in a specific population are spread out. It is the average of the distances from each data point in the population to the mean, squared. Here N isthe population size and the xiare data points. μ is the population mean. ...

F = kq1q2/r^2 describes the force between oppositely charged particles. This means that the force has an inverse squared relationship to the distance between two particles. If the F = 1 when r = 1, what will F equal when r = 3? (all other values held Find the attractive force (in...
