Question

What happens to the shape of the chi-square

distribution as the df value increases?
a. The mode (highest point) of the distribution moves
to the right.
b.The mode (highest point) of the distribution moves to
the left.
c.The mode (highest point) of the distribution does not
move, but the distribution becomes more spread out.
d. The mode (highest point) of the distribution does not
move, but the distribution becomes more tightly
clustered around the mode.

Answer 1

C

Step-by-step explanation:

The mode (highest point) of the distribution does not move, but the distribution becomes more spread out. As the degrees of freedom (df) value increases, the shape of the chi-square distribution becomes more spread out, with the mode remaining at the same point.
