The data were also analyzed using chi-square test. The chi-square result shows that there is no significant relationship between internal locus of control and problem solving ability while significant relationship was found between external locus of control and problem solving ability. In-service teachers with internal locus of control had a higher problem solving ability and those with external locus of control had a lower problem solving ability. Also with chi-square test, no significant relationship was found between in-service teachers with low mathematics anxiety and problem solving ability whilst significant relationship was found between in-service teachers with high mathematics anxiety and problem solving ability
