So far we've been using statistics to mostly describe a sample. But we can do so much more with what we've learned about probability and the Standard Normal Curve. I'll show you!
For example, consider the overall mean for all of the scores in the no reward group, we found that to be 6.6 Now, was the mean for each no-reward group in the whole design a 6.6? Then we subtract the ...For example, consider the overall mean for all of the scores in the no reward group, we found that to be 6.6 Now, was the mean for each no-reward group in the whole design a 6.6? Then we subtract the mean for the distraction group, and the mean for the reward group, and then we add the grand mean.
From algebra recall that the slope is a number that describes the steepness of a line, and the y-intercept is the y coordinate of the point (0,a) where the line crosses the y-axis. In...From algebra recall that the slope is a number that describes the steepness of a line, and the y-intercept is the y coordinate of the point (0,a) where the line crosses the y-axis. In the equation y=a+bx, the constant b that multiplies the x variable (b is called a coefficient) is called the slope.
