In a study with four groups and 10 participants in each group, the sum of squares for the between-groups source of variation is

Stells [14]

Answer:

Step-by-step explanation:

Given that:

The study group n = 4

number of participants = 10

the sum of squares for the between-groups source of variation is 60

The objective is to determine the mean square between groups in this study

The mean square between groups in this study compares the means of the group with the sum of squares for the between-groups source (i.e the grand mean)

For this analysis;

the degree of freedom = n-1

the degree of freedom = 4 - 1

the degree of freedom = 3

Thus; the mean square between groups = $\dfrac{60}{3}$

the mean square between groups = 20

Two statements are logically equivalent when:

-BARSIC- [3]

<h2>Answer:</h2>

C. The two statements agree in point of truth or falsehood in virtue of their logical structure alone, i.e. the two statement are true or false in exactly the same conditions.

<h2>Step-by-step explanation:</h2>

For two statements to be logically equivalent, their truth values (true or false) must be the same for every variation of their constituent variables. In other words, if the truth tables of both statements are the same for every possible value of their variables, then they are logically equivalent.

For example;

<em>The two statements P ∩ (Q U R) and (P ∩ Q) ∪ (P ∩ R) are logically equivalent. </em>

If P, Q and R are all true, then;

<em />

If P, Q and R are all true, then;

<em>P ∩ (Q U R) = false</em>

<em>(P ∩ Q) ∪ (P ∩ R) = false</em>

<em />

If P = false, Q = true and R = true, then;

<em>P ∩ (Q U R) = false</em>

<em>(P ∩ Q) ∪ (P ∩ R) = false</em>

<em />

Checking for all other possible combinations of truth values of P, Q and R will always give the same results for the two statements, therefore, they are logically equivalent.
