A point estimate is a single value estimate of a parameter.For instance, a sample mean is a point estimate of a population mean. The only way for causation to be established is by conducting an experiment. While there are many measures of association for variables which are measured at the ordinal or higher level of measurement, correlation is the most commonly Face validity and content validity are similar in that they both evaluate how suitable the content of a test is. From those measurements, a trend line can be calculated. The most typical comparison is a Pearson Product Moment Correlation and is shown as a correlation coefficient value of r.
