Question

To assess the effectiveness of responses to bad behavior among children, a researcher has the child’s teacher respond one of three ways to the first incident of bad behavior: The teacher punishes the child; the teacher turns-the-other-cheek (ignores the behavior); or the teacher gives the child strong warning about the consequences of such behavior. The researchers then measure how often additional bad behaviors. They find that when the teacher always punishes the child or turns-the-other-cheek, the child engages in more bad behaviors than when the teacher merely warns about the consequences of the bad behavior.

Which of the following is the null hypothesis?

Ho: µ₁ = µ₂ = µ₃

H₁: M1 ≠ M2 ≠ M3

Answer 1

Null hypothesis states that there is no significant difference between the results for the three conditions .It is denoted by the sign Ho. Therefore the correct answer here would be option A
