Reaction Time

The data were first treated with descriptive statistical measurements to evaluate for the patterns and behaviour in the observations . Correlation analysis was done also for the gender-reaction time relationship

The reaction time was just a derived data obtained from the formula d 1 /2 g t2 where the equation for time , t was derived from

d the distance the object fell

g the acceleration of gravity (-9 .8m /s /s

t the time the object was falling

t SQRT d /-4 .9m /s /s The results of the descriptive statistical

analysis are summarized on the table Table 1 . Descriptive statistical data for distance

The mean of 20 .46947 for the distance was calculated . The deviation of the measurements from the mean was 7 .181951 with a variance of 51 .58042 Kurtosis and skewness were found to be -0 .01521 and 0 .161602 , implying that the observations are mostly on a lower distance with the values thoroughly scattered because of the platykurtic behaviour dictated by the negative kurtosis . The mode of the measurements from the respondents was 22 cm and a median of 21 cm . The values of the central tendencies can give us a rough estimate of the precision of the measurements even for the whole data not considering...
