Experiment B: Digit Span (10 points) The second experiment focused on recall. In the Digit Span Test, in which they were required to repeat a sequence of digits following the presentation order (maximum possible= 8 digits). Participants were presented with two sequences for each length, starting with a series of two digits. The task was stopped when the participant failed both sequences of a given length. The score was defined by the number of digits of the longest recalled sequence. There were three versions of the digit task. The following data was collected: Vivaldi Mean = 5.3 Std. Dev. = 1.0 n = 24 White Noise Mean = 4.7 Std. Dev. = 0.9 n = 24 Using a = .05, test the claim the variations between the three data sets are the same using an ANOVA (null is the claim!).
