Answer:
In a one-way ANOVA, the 
is calculated by taking the squared difference between each person and their specific groups mean, while the 
is calculated by taking the squared difference between each group and the grand mean.
Step-by-step explanation:
The one-way analysis of variance (ANOVA) is used "to determine whether there are any statistically significant differences between the means of two or more independent groups".
The sum of squares is the sum of the square of variation, where variation is defined as the spread between each individual value and the mean.
If we assume that we have p groups and each gtoup have a size 
then we have different sources of variation, the formulas related to the sum of squares are:
A measure of total variation.
A measure of variation between each group and the grand mean.
A measure of variation between each person and their specific groups mean.
Answer:
Between 85 and 100
Step-by-step explanation:
Getting this will get the average between the required numbers since the average of 83 and 87 is 85, getting 85 will keep the answer at 85 and getting 100 will get the average at 90.
Answer:
Ray, you need the slope-intercept formula y=mx+b
Step-by-step explanation:
Next you'll need 2 points, any points are fine. Just find two easy ones along the line. I'll just pick Point 1 as P1 = ( 0,4) and point 2 as P2 = (4,0) because they are easy to work with.
next use
point P1 (0,4) in the form (x1,y1)
point P2(4,0) in the form (x2,y2)
slope = m
m = (y2-y1) / (x2-x1)
m = (0-4) / (4-0)
m = -4 / 4
m = -1
now use the point slope with one of the points, to find the slope-intercept form.
y - y1 = m(x -x1)
y - 4 = -1(x-0)
y -4 = -x
y = -x + 4
note:
y = mx +b
y = (-1)x + b is the form. see?
