Same Data, Same Formula, But different mean.

[Szaboteur]

Hello all,

I do not know where my mind is playing tricks. Mind or math, not sure.

This is the formula that i used to average (with blue color) all the rows and all the columns in the data set (with black collor): =IFERROR(AVERAGEIF(K55:P55,"<>0",K55:P55),"")
But in the same data, if i calculate mean on column this result 4.17. On the other side, when i calculate total mean horizontally, the mean becomes 4.20. In the first place, i thought that the 0 makes the difference. Horizontally to take it as a number and vertically not. But... this is not the answer.

I dont know why it didn't appeard. But 0 means the participant scored CANNOT JUDGE<cannot judge="">. No value means he gave up. 1 means the minim score for a behavior. 5 means - observed always.</cannot>
