Median of hourly wage rate at 6.25 (in 1978 US $). The dispersion (inter-quartile range) of
hourly wage rates was found to be 3.64 (in 1978 US $). Distribution of hourly wage rate of
females was found to be almost normal with slight positive skewness (S = 0.67) with median of
hourly wage rate at 5.0 (in 1978 US $). The dispersion (inter-quartile range) of hourly wage rates

the first quartile of the range of their hourly wages, indicating presence of outlier hourly wage
for few males. Females’ hourly wages were almost normally distributed in the range of their
hourly wages, indicating symmetric division of hourly wages for females.
