 * Topic:** Reaction Time


 * Question:** What gender has a faster reaction time?


 * Background Information:** "At the risk of being politically incorrect, in almost every age group, males have faster reaction times than females, and female disadvantage is not reduced by practice Noble 1964 Welford, 1980//.//, 1999; Dane and Erzurumlugoglu, 2003; Der and Deary, 2006. The last study is remarkable because it included over 7400 subjects. Bellis 1933 reported that mean time to press a key in response to a light was 220 msec for males and 260 msec for females; for sound the difference was 190 males to 200 females. In comparison, Engel 1972 reported a reaction time to sound of 227 msec male to 242 msec female. However, things may be changing--Silverman 2006 reported evidence that the male advantage in visual reaction time is getting smaller especially outside the US, possibly because more women are participating in driving and fast-action sports. Botwinick and Thompson 1966 found that almost all of the male-female difference was accounted for by the lag between the presentation of the stimulus and the beginning of muscle contraction. Muscle contraction times were the same for males and females. In a surprising finding, Szinnai //et al.// (2005) found that gradual dehydration (loss of 2.6% of body weight over a 7-day period) caused females to have lengthened choice reaction time, but males to have //shortened// choice reaction times. Adam //et al. (//1999) reported that males use a more complex strategy than females. Barral and Debu 2004 found that while men were faster than women at aiming at a target, the women were more accurate. Jevas and Yan (2001) reported that age-related deterioration in reaction time was the same in men and women". **"** Simple reaction time shortens from infancy into the late 20s, then increases slowly until the 50s and 60s, and then lengthens faster as the person gets into his 70s and beyond (Welford, 1977; Jevas and Yan, 2001; Luchies //et al.//, 2002; Rose //et al.//, 2002; Der and Deary, 2006. Luchies 2002 also reported that this age effect was more marked for complex reaction time tasks, and Der and Deary 2006 concurre."


 * Hypothesis:** I think males are faster then females because the female they have a slower reaction time then males.


 * Procedure:**
 * 1) Get 10 Males And 10 Females
 * 2) Find the reaction time game
 * 3) Make sher that the computer game is up on the computer game were you went them to sit at
 * 4) The people that is playing the game that you pick tell them how to play the game
 * 5) Click the mouse as soon as you see the baseball and then you hit the mouse and then the play again on the left side of the screen.
 * 6) Play the game 3 Times
 * 7) Record the 3 times they swing and write it on the

 * Data/Results:**

I think male are faster then females. My Hypothesis was right because I said that male are faster then female because Some girls are not all that fast but some of them are really fast but not all of them are that fast. Will same people did not know what to do in the experiment but that is ok that. The date is the spreadsheet.
 * Conclusion**
