Ho: There is no statistically significant difference in Mg in the pottery form different sites. The alpha level for
this is 0.5, with the dependent variable being Mg, independent variable being the four different sites.
Ha: These is a statistically difference in Mg in the pottery from the different sites. The alpha level is 0.5, with
the dependent variable being Mg. independent variable being the site where it was found.
Alpha level:0.5
IV: the site where the pottery was cultivated.
DV: the nitrate we car comparing, Mg
Methods: We had to select what type of test we are doing. We started by eliminating the t test, and using the
ANOVA. We wanted to use ANOVA because its comparing the means of two variables. Then we did
descriptive statistics on out dependent variable, then created a frequency count histogram.
Results& Conclusion: The derived F = 34.45 exceeds the tabled critical value of F =3.049 at p = .05 with df1 =
3 and df2 = 22. Therefore, H0 is rejected, and it is concluded that at least one mean is significantly different from
one other mean.
