The test examines not only one's ability to read and write kanji, but also one's ability to understand their meanings, to use them correctly in sentences, and to identify their correct stroke order.
Prevalence = (2 + 1) / 203 = 0.0148 or 1.48%; The individual's pre-test probability was more than twice the one of the population sample, although the individual's post-test probability was less than twice the one of the population sample (which is estimated by the positive predictive value of the test of 10%), opposite to what would result by ...
[1] The test is appropriate for individuals aged 5 years through adult. The WRAT5 provides two equivalent forms (Blue and Green), which enables retesting within short periods of time without potential practice effects that occur from repeating the same items. The alternate forms also may be administered together in a single examination. [1]
where S is the standard deviation of D, Φ is the standard normal cumulative distribution function, and δ = EY 2 − EY 1 is the true effect of the treatment. The constant 1.645 is the 95th percentile of the standard normal distribution, which defines the rejection region of the test. By a similar calculation, the power of the paired Z-test is
