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.
The skewness for a normal distribution is zero, and any symmetric data should have a skewness near zero. Negative values for the skewness indicate data that are skewed left and positive values for the skewness indicate data that are skewed right.By skewed left, we mean that the left tail is long relative to the right tail. Similarly, skewed right means that the right tail is long relative to the left tail.kewness is a measure of symmetry, or more precisely, the lack of symmetry. A distribution, or data set, is symmetric if it looks the same to the left and right of the center point. Kurtosis is a measure of whether the data are peaked or flat relative to a normal distribution.
