conditions with a 0.7 proportion
of between-unit variance, sample sizes of approximately 1500 are needed
with 5 repeated measures, whereas sample sizes upwards of 1700 are
needed for 4 repeated measures. Based on these results, the following
experimental conditions for validation are selected: The range of sample
sizes is reduced to 900 to 1800, and experimental conditions with 3
repeated measures are omitted. This results in a total of 10 sample
sizes <span class="math inline">\(\times\)</span> 2 numbers o
