One-way ANOVA and two-way ANOVA are different because: a. The single factor in one-way ANOVA has only one level.
b. Each factor in the two-way ANOVA has exactly two levels.
c. The one-way ANOVA concerns a single factor with multiple levels and the two ANOVA concerns two factors with also multiple levels.
d. The one-way ANOVA concerns a single factor with a single level and the two ANOVA concerns two factors with a single level each.

c. The one-way ANOVA concerns a single factor with multiple levels and the two ANOVA concerns two factors with also multiple levels.

Step-by-step explanation:

The main difference between one way anova and two way anova is that one way anova has a single independent variable and two way anova has two independent variables.

The dependent variables may vary . They may be one , two or three. They do not affect the method used.

So  one-way ANOVA concerns a single factor and  the two ANOVA concerns two factors.

So the best choice is option c.

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

even numbers are divisible by more than 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb
