incorrect acc %
Hi, help I have a problem with the correct calculation of the accuracy.
My experiment has 3 difficulty levels per span length (span 2, span 3 and span 4). Each level has 1 practice_loop (with 10 trials) and 1 experimental_loop (with 20 trials).
Every trial consists of 2, or 3 or 4 target numbers 1 to 9 (each in a cell) and 4 or 5 mathematical operations (-2 to + 2 except 0). The subject must apply the operations presented in the cells and continuously update the information in each cell. After the 4 or 5 operations the subject has to type the final results respectively in each cell and in the right cell (both the intermediate results and the final results range from 1 to 9). In 5 trials there are 4 operations and in other 5 trials there are 5 operations. I designed my loop tables in Excel, directly using the files as input.
This is the first block (practice span 2):
Before each block I inserted an inline script (prepare) (this is for practice span 2):
At the end of this practice_loop_span_2 I get 25% accuracy. At the end of the experimental_loop_span_2 acc 75 %, practice_loop_span_3 acc 112,5 %, experimental_loop_span_3 acc 187,5 %, practice_loop_span_4 acc 237,5 %, experimental_loop_span_4 acc 315 %.
Help me please,
