In a one-way ANOVA, the __________ is calculated by taking the squared difference between each person and their specific groups
guapka [62]

Answer:

In a one-way ANOVA, the SS_{within} is calculated by taking the squared difference between each person and their specific groups mean, while the SS_{between} 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 n_j then we have different sources of variation, the formulas related to the sum of squares are:

SS_{total}=\sum_{j=1}^{p} \sum_{i=1}^{n_j} (x_{ij}-\bar x)^2

A measure of total variation.

SS_{between}=\sum_{j=1}^{p} n_j (\bar x_{j}-\bar x)^2

A measure of variation between each group and the grand mean.

SS_{within}=\sum_{j=1}^{p} \sum_{i=1}^{n_j} (x_{ij}-\bar x_j)^2

A measure of variation between each person and their specific groups mean.

This is my work so far but I believe I’m doing it wrong. I have to, “Solve for X in the diagram”. Need help ASAP
Lorico [155]
X + 8 = 60 + 94.

This is geometrically correct, now you must solve the algebra portion.

60 + 94 is just 154, which means x + 8 = 154.

What number + 8 = 154? It must be 146.

Need help please thanks
tekilochka [14]
I'm guessing d b are equal and a and c are equal or I don't think we would be able to solve so going on that
if angle d is 57 angle b must also be 57
A parallelegram has angles that add up to 360
So 360= 57+57+2c
Solve
360=114+2c
-114 both sides
246=2c
÷2 both sides
123=c
