4. Are there outliers among the values of age? Provide a rationale for your answer. It’s a subject that’s

unusually high or low from the mean simple calculation. An outlier can mess around with a data and

make the interpretation outcomes difficult. If you find an outlier you can also find an interquartile range

of the distribution and an outlier age that’s about 1.5 times outside the interquartile range.

Percentiles 25 40.00

50 52.50

75 79.00

The interquartile range is 39.00.

Lower bound for Outlier = 40 .00 – 1.5*39.00 = -18.5

Upper bound of Outlier = 79.00 +1.5*39.00 = 137.5

Since all age’s are within the upper and lower hence there are no Outlier’s.

5. What is the range of age values? When the lowest age is calculated by the highest the range is 51
