2022 Freshman Meet 1

The freshmen written topic for meet 1:

Sections: 1.3 and 2.1-2.5 in the online Introductory Statistics (OpenStax) text.

Measures of central tendency (mean, median, and mode), histograms, box-and-whisker plots, stem and leaf plots, range, interquartile range (IQR), potential outliers. No variance. No standard deviation. No comparison of sample and population means.

Here is a chart showing the association of topics with sections in the text.

 Section Topics 1.3 Frequency, relative and cumulative 2.1 Stem and leaf graphs ("plots" in our standard usage). Contestants are assumed able to read line and bar plots . 2.2 Histograms (not "frequency polygons" or "time series graphs") 2.3 Quartile, percentile, median, interquartile range (IQR), potential outliers(!) 2.4 Box plots. 2.5 Mean, mode, grouped frequency tables. Excluded: population mean (x vs mu)
