# ANOVA result indicated that there were sig. differences while Tukey post-hoc test revealed that there were no statistically sig. differences [duplicate]

I was conducted one-way ANOVA analysis to examone the level of knowledge shaorng among the employees based on there age differences. One-way ANOVA indicated that there were significant differences in the level on KS while Tukey post-hoc test revealed that there were no statistically significant differences on the level of knowledge sharing between the groups based on the respondent's age differences.

So, what is the conclusion of this result and why the result shows a different result? AND, how do i interpret this result? Table: Mean Scores on Level of Knowledge Sharing among Employees - Based on Age.

Age No. Mean    SD
20-29   34  3.82    1.13
30-39   54  3.87    0.92
40-49   56  3.41    1.06
over 50 45  3.32    1.24
