Given $200$ measurements ranging from $1.31$ to $2.95$, how would you group them into a frequency distribution with 6 classes? Give the class limits as well as the class midpoints.
You were lucky enough to be dispatched to study the Southern Royal Albatross population. A sample of $30$ albatrosses had the following wingspans $cm$:$$ \begin{array}{llllllllll} 324 & 291 & 286 & 290 & 365 & 294 & 311 & 336 & 288 & 299 \\ 277 & 307 & 314 & 296 & 288 & 301 & 278 & 328 & 321 & 279 \\ 321 & 330 & 319 & 298 & 287 & 324 & 308 & 316 & 294 & 312 \end{array} $$Organize this data into a frequency table with $6$ classes. Draw a histogram of the wingspans.
Consider the following $24$ measurements of interorbital width of a sample of domestic pigeons.$$ \begin{array}{llllllll} 12.2 & 12.9 & 11.8 & 11.9 & 11.6 & 10.9 & 11.1 & 12.3 \\ 12.7 & 13.0 & 11.4 & 11.6 & 11.6 & 10.0 & 11.7 & 12.8\\ 11.2 & 12.3 & 13.1 & 12.9 & 12.6 & 10.4 & 11.0 & 11.6\end{array} $$Organize this data into a stem-and-leaf display.
