group of scores is plotted along the vertical axis. If the height (frequency)
increases as you go from left to right, the low scores on the left have a smaller
frequency than the high exam scores on the right.
Suppose you gathered data for the money spent ($ millions) over a 100-year
period in five different geographical regions in the U.S. What graph would best
display your findings? - {✔✔ANSWER✔✔}-3D or three-dimensional graphs
are more effective when used for three-dimensional data rather than two-
dimensional data.
In this situation, there are three dimensions: $ millions spend, years, and
geographic regions. Therefore, a three-dimensional graph would best display the
data.
What is the definition of mean? - {✔✔ANSWER✔✔}-the average value;
affected by outliers
What is the definition of median? - {✔✔ANSWER✔✔}-middle value when all
scores are listed in ascending order; not affected by outliers
What is the definition of mode? - {✔✔ANSWER✔✔}-the value in the dataset
with the greatest frequency; not affected by outliers
