1 _ 1 ___45 __

1 _ 2 __ 51 __

1 _ 3 __ 72 __

1 _ 4 __ 50 ______________56 ____ 36

2 _ 1 __ 49 ______________57.67__ 75.17

2 _ 2__ 45 ______________57 ____ 144

3 _ 3__ 70 ______________51.33__ 348.57

3 _ 4 __56 ______________56.67__0.45

MSE = Σ(Pt - Ft)² ÷ n

MSE = (36+75.17+144+961+13.47+300.33+0.11+348.57+0.75) ÷ 9

= 208.82

0.985 rounded to the nearest tenth
GarryVolchara [31]
They always try to trick you with this.  Remember anything 5 or above would round up, anything 4 and under would round down.  So look for the tenth place.  that's the 9.  The number to the right is 8 which is greater than 5.  That means round up.  You can't round it to 0.1 because that takes it back down.  So you just move it over.  The answer is 1.0.
