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.

The equation of the line of best fit of a scatter plot is y = 12x + 7. What is the slope of the equation?

g100num [7]

Hey There,

@Okayjimz2003ov47ik

The slope in this equation is 12.

Look at the number in front of the X to determine the slope.

Brandy solved 1/6/ 5 using a related multiplication expression. What multiplication expression did she use?

Advocard [28]

<h3><u>Question:</u></h3>

Brandy solved 1/6÷ 5 by using a related multiplication expression. which multiplication expression did she use

<h3><u>Answer:</u></h3>

The expression that she can use is $\frac{1}{6} \times \frac{1}{5}$

<h3><u>Solution:</u></h3>

<em><u>Given that Brandy solved the following expression</u></em>

$\frac{1}{6} \div 5$

We have to find the multiplication expression she used

From given expression,

$\frac{1}{6} \div 5$

We can convert the division symbol to multiplication

Convert the fraction division process to a multiplication process by using the following steps:

Change the “÷” (division sign) to “x” (multiplication sign) and invert the number to the right of the sign.

Multiply the numerators. Multiply the denominators

Therefore,

$\frac{1}{6} \div 5 = \frac{1}{6} \times \frac{1}{5}$

$\frac{1}{6} \div 5 = \frac{1}{6} \times \frac{1}{5} = \frac{1}{30}$

Thus, the expression that she can use is $\frac{1}{6} \times \frac{1}{5}$
