CONCLUSION

The mean for years of work experience in this sample is 18.21 years while the median is 15 years.The distribution is slightly skewed to the right. The mean and median for looks was approximate 3, when the mean = the median that suggest that all samples are equal. The Looks data is normally distributed.The distribution above the mean is symmetrical to the distribution below the mean. Similarly, lwage and years of education are normally distribution.This suggest these data do not have extreme values and/or have a flatter dome, which means they have wide standard deviation. The standard deviation for both looks and lwage is below 1, not very wide.The standard deviation for education is estimate 3 years which is small under the curve. Implication: The samples under these columns are equal. ## Including Plots

You can also embed plots, for example:

Note that the echo = FALSE parameter was added to the code chunk to prevent printing of the R code that generated the plot.
