If you have two data sets with the following information.
Both data have a mean of 100.
In Data set one:
The 25th quartile 50, the 50th is 100, and the 75th is 150.
Data set two:
The 25th quartile 75, the 50th is 100, and the 75th is 300.
Which data set is more symmetric and why do you think that?

Suppose you have two individual cross-sectional data sets on car prices for the years 2002 and 2004 covering the time periods both before and after the U.S. invasion of Iraq in 2003. You have 130 observations in your 2002 data set and 90 observations in your 2004 data set. You have decided to append your two individual cross-sectional data sets together to form one pooled cross-sectional data set. After appending the two data sets, you now have 220 total observations...

You have generated two sets of vesicles, both with bacteriorhodopsin (which pumps protons out of bacteria in response to light) and the mitochondrial F1 ATPase inserted into the membranes of the vesicles. In both cases, the parts of the proteins that normally face the outside of the cell or the mitochondrial intermembrane space are inside the vesicles, and protons, ADP and inorganic phosphate are outside the vesicles. Both sets of vesicles are incubated with light, but one set also has...

Suppose you have two data sets, each of which contain n comparable elements. As an basic operation, you may ask one set to tell you the kth largest element of that set, for a value k you choose. Give an algorithm that, with O(log n) queries, determines the median value of the union of the two sets.
