Consider as SAMPLE data:
52,84,86,91,96,96,98,100,103,105,109.
1) What graph is better - bar graph or histogram?
2) What's sum of squares?
3) What's sample standard deviation?
4) What's sample variance?
Now, consider as POPULATION data:
52,84,86,91,96,96,98,100,103,105,109 (same).
1) What's sum of squares?
2) What's population standard deviation?
3) What's population variance?
