### Question:
BasicStandardisedMeanDifference extends AbstractBasicRelativeEffect<ContinuousMeasurement> { double getCorrectionJ() { return (1 - (3 / (4 * (double) getDegreesOfFreedom() - 1))); } BasicStandardisedMeanDifference(ContinuousMeasurement baseline,
			ContinuousMeasurement subject); @Override Double getError(); String getName(); Distribution getDistribution(); @Override AxisType getAxisType();  }### Answer:
@Test public void testGetCorrectionJ() { double expected = 1 - (3 / (4 * ((double) d_sampleSize - 2) - 1)); assertEquals(expected, d_smd.getCorrectionJ(), 0.0001); }
