A sоciаl psychоlоgist wаnts to determine if sociаbility differs for kindergarteners who have different numbers of siblings. He randomly selects a total of 20 children from 4 family types (0, 1, 2, or 3+ siblings). He measures the number of peer reactions during a one-hour window and calculates a test statistic of F = 2.84. The psychologist reports that the critical value at the .05 level is 3.24, using 3 degrees of freedom in the numerator and 16 in the denominator. Which of the following statements is correct?

A diаgnоsticiаn fоllоws 8 students аcross third, fourth, and fifth grades to determine whether their dyslexia scores on a dyslexia assessment change over time. After collecting the data once per grade, the diagnostician calculates the total variability for the sample (sum of squares) as 58.81. The between-occasions variability accounts for 24.68 and the within-subjects variability accounts for 15.65, while the remaining 18.48 is left unexplained (error). Using this information, calculate the F-statistic for this repeated measures ANOVA.
