Other Causes of Hypothyroidism. In some cases, hypothyroidism results from a problem with the pituitary gland, which is at the base of the brain. This gland produces thyroid-stimulating hormone (TSH), which tells the thyroid to do its job. If your pituitary gland does not produce enough TSH, levels of thyroid hormones will fall.
Partial eta-squared is a measure of variance, like r-squared. It tells us what proportion of the variance in the dependent variable is attributable to the factor in question. You can get these measures by choosing the 'Estimates of effect size' option when setting up an ANOVA.s mentioned above, partial eta-squared is obtained as an option when doing an ANOVA and r or R come naturally out of correlations and regressions. The only effect size you're likely to need to calculate is Cohen's d. To help you out, here are the equations.
For ANOVAs, two of the most popular are Eta-squared and partial Eta-squared. In one way ANOVAs, they come out the same, but in more complicated models, their values, and their meanings differ. SPSS only reports partial Eta-squared, and in earlier versions of the software it was (unfortunately) labeled Eta-squared. More recent versions have fixed the label, but still donât offer Eta-squared as an option. Luckily Eta-squared is very simple to calculate yourself based on the sums of squares in your ANOVA table.
