15. Two horses A and B, were tested according to the time (in seconds) taken to run a particular
      tract with the following results.
Horse A:          28,       30,      32,      33,       29        and      34
Horse B :         29,       30,      30,      24,       27        and      29
    Analyses the above data and Report whether or not you can discriminate between the running
    times of two horses.
16. Briefly Explain the Norms for using Tables, charts and diagrams.

Section-D
                                  (Compulsory)               (1 ´ 15 = 15)
Professor Stevens is designing an experiment to determine the effect of intensity of tone on reaction time. He believes that participants will respond more quickly to more intense tones. He wishes to use five intensities of tone: 10,30,50,70, and 90 dB.

He expects there will be a practice effect such that participants will get faster over the first 20 or 50 trials. (A trial is a presentation of a single tone.) He is able to present a trial every 10 seconds. Participants will be available for 1 hour, including the time taken in introducing them to the experiment, practicing, and debriefing. He estimates that he may be able to collect data for up to 30 minutes.
He has reason to believe that reaction time might differ between the left and right hard. It is likely that people are faster with their preferred hand. About 5% of people are left- handed, but left handedness is more common in men than in women. He has no theoretical interest in differences between left and right hand, the effects of handedness or sex differences.
Professor Stevens wonders whether to use a within – subjects or between – subjects design. The within – Subject design would require him to decide which order of presenting the stimuli to the subjects would be best. If he used a between subjects design, he would not have that problem, but he would require more participants to complete the experiment.
If he uses a between – Subjects design each participant would experience only one intensity. He links that he would need at least 20 different individuals at each intensity to control for individual differences between subjects.
If he uses a within – Subjects design, he could use reverse counter balancing, a Latin Square, random order, only increasing order, or only decreasing order. He realizes that each one has certain advantages and disadvantages.
It he randomizes the order or uses Latin Square loud tones will follow soft ones, and vice versa, in an unpredictable manner. This might startle the participants, causing them to be possibly faster on the loud tones. Or slower, depending on whether the startle reaction is compatible with pressing the key on the computer. Then again, presenting the tones in a predictable sequence might make the participants “tone out” or habituate to, the effects of intensity.
He believes that he needs 100 trials per stimulus in the total experiment to obtain reliable results.
Required Decide:
a) Whether to do the experiment within or between subjects.
b) What sort of order to use, if is to be done between subjects.
c) Whether to control for hand and handedness, and if so, how
d) How many participants to use.
Justify each of your decisions, summarize your decisions by showing the total number of stimulus present acting how they are distributed across participants and in what order. (It is not necessary to list the exact order for all trials and participants – Just give the Schema).
