Assignment Help Basic Statistics

Reference no: EM1318371

Create histograms for both frequencies, showing values on top of the bars, and the correct annotation on both axes. In particular, be sure that the x-axis is properly labelled.

Evaluate your histograms for any outliers in your data. Based on your evaluation of outliers, you may trim no more than 1% of the data contained in the data set. This must be done symmetrically (i.e., trimming no more than 0.5% off the top and 0.5% off the bottom).

Reproduce the histograms with the data points that remain after you have completed your trimming. Analyse the mean, median, and standard deviation of the trimmed data. What change did the trimming make in these measures?

All the rest of the calculations for this portion of the project should be completed with this trimmed data.
