Statistics

I was given a sample data set of systolic blood pressures andwas asked to 1.) calculate: the mean, median, standard deviation,interquartile range and 2.) applied what I have learned in thecourse to describe or comment on the systolic blood pressuresdata.
minimum : 86.0
maximum : 267.0
mean: 140.2
median: 137.0
standard deviation: 22.92012
Q1: 123.0
Q3: 154.0
After calculating the IQR with lower limit of 76.5 and upperlimit of 200.5, I stated that given the maximum value of systolicblood pressure of 267.0, there are outliers in this sample andbecause there are outliers, median and IQR should be used tosummarize typical value and variability rather than the mean andstandard deviation. Is my assessment correct? Additionally, how canI interpret the median value in this example and connect that tosystolic blood pressures? Like, is it accurate to say that theaverage systolic blood pressure in this sample is 137 (which is themedian value)?Â Â
