Identify the level of measurement of the data, and explain what is wrong with the given calculation. In a set of data, mood levels are represented as 0 for bad, 1 for OK, and 2 for good. The average (mean) of the 637 mood levels is 0.9.

Level of measurement=ordinal level

Average mean cannot be calculated for ordinal type of data.

Step-by-step explanation:

The level of measurement for mood levels is ordinal level because there is ordering in the data. It means that 0,1,2 represents the ranking of mood level from bad to good.

Furthermore, the average calculated for mood level 0.9 doesn't meaningfully represents the data. The average can't be interpreted in the context.

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
