Are there commonly accepted ways to visualize the results of a multivariate regression for a non-quantitative audience? In particular, I'm asking how one should present data on coefficients and T statistics (or p-values) for a regression with around 5 independent variables.

I personally like dotcharts of standardized regression coefficients, possibly with standard error bars to denote uncertainty. Make sure to standardize coefficients (and SEs!) appropriately so they "mean" something to your non-quantitative audience: "As you see, an increase of 1 unit in Z is associated with an increase of 0.3 units in X."

In R (without standardization):

foo <- data.frame(X=rnorm(30),Y=rnorm(30),Z=rnorm(30))
model <- lm(X~Y+Z,foo)

coefs <- coefficients(model)
std.errs <- summary(model)$coefficients[,2]
