To test whether arousal or stress levels increase as the difficulty of a task increases. eight participants were asked to complete an easy, typical, or difficult task. Their gal- vanic skin response (GSRI was recorded. A GSR measures the electrical signals of the skin in units called microSiemens Si, with higher signals indicating greater arousal or stress. The data for each task are given in the table 4 6 11 6 8 9 11 7 6 8 11 8 10 10 10 7 11 Easy Difficulty of Task Typical 5.6 Difficult 26 90 8.9 39 45 5.8 2.4 3.7 3.5 1.2 20 78 la) Complete the F table. b) Compute Tukey's HSD post hoc test and interpret the results. 25. Iconic memory is a type of memory that holds visual information for about half a second 10.5 second). To demonstrate this type of memory. participants were shown three rows of four letters for 50 milliseconds. They were then asked to recall as many letters as possible, with a 0- 0.5-, or 1.0-second delay before responding. Researchers hypothesized that longer delays would result in poorer recall. The number of let- ters correctly recalled is given in the table. 2.1 3.3 6.4 12 4.6 75 1.8 3.1 44 2.2 20 3,8 Delay Before Recall 0 0.5 1.0 lal Complete the Ftable. Ibl Compute Fisher's LSD post hoc test and interpret the results 27. An educator wants to evaluate four different methods aimed at reducing the time children spend "off task in the classroom To test these methods, she implements one method in each of four similar classrooms and records the time spent off task in minutes in each classroom. The results are given in the table 4 12 8 4 11 4 2 8 10 5 TO G
