Question
Construct the one-way ANOVA table.
The table below shows the results of hardness measurements of three welds using three fluxes, an engineer needs to find if there are differences in the population mean hardness among the three flux types. Which of the following one-way ANOVA table is absolutely correct and why?
Table: Hardness of welds using different flux
Construct the one-way ANOVA table.
The table below shows the results of hardness measurements of three welds using three fluxes, an engineer needs to find if there are differences in the population mean hardness among the three flux types. Which of the following one-way ANOVA table is absolutely correct and why?
Table: Hardness of welds using different flux
Flux A Flux B Flux C 250 254 258 260 265 264 239 263 253Explanation / Answer
The table value of F at 0.05 with (2,6) is 5.14. Fcal<Ftab, so we accept null hypothesis. Therefore, there is no differences in the population mean hardness among the three flux types.
