WebJul 23, 2008 · Association coefficients are tools in data analysis that measure the strength of a relationship between two variables. A traditional measure for the 2 × 2 table is the tetrachoric correlation (Pearson, 1900; Divgi, 1979).The coefficient is an estimate of the Pearson product-moment correlation coefficient between hypothetical row and column … WebMoreover, the full range of the pendulum has a magnitude of 2A. Besides, the periodic motion also applies to the waves and springs. In addition, the sine function oscillates between values of +1 and -1, so it is used to describe periodic motion. Most noteworthy, the unit of amplitude is a meter (m). Get the huge list of Physics Formulas here
