January Blog Problem of the Month

Monica Meanless and Abraham Average are just regular kids from Statisticsville, Mathalopolis. They both love sports! All kinds of sports! But sometimes when they are talking to their friends about their favorite sports, it sounds like their friends are on another planet. They just don’t understand.

In baseball they wonder about batting averages, on-base percentages, winning percentages, and slugging average. In football they wonder about quarterback completion rate, quarterback rating, average yards per carry, average yards per touch and how offensive and defensive rankings are figured out. In basketball there is that whole free throw percentage thing. In hockey they wonder what “shots on goal” means. Please help Monica Meanless and Abraham Average enjoy even more the sports they love by explaining one of the above (or any other statistical item from any other sport – they really love sports) to them.

If someone else explains something, you can put it in your own words or add to the explanation.

 

November Blog Problem of the Month

We have a big break coming up at the end of November! Many families will celebrate Thanksgiving. Just about everyone will get together with relatives and maybe some friends. Find out what your family is planning. Are you having a big celebration at your house on Thanksgiving? Are you going to a relative’s house on Thanksgiving? Are you going out to eat somewhere? Are you going to a friend’s house on Thanksgiving? Figure out (ask parents to help) how many people in total do you expect to be there. Make sure to include all brothers, sisters, parents, aunts, uncles, cousins, grandparents, friends of the family [FOF], and anyone else. How many of them are male? How many are female? How many are age 10 and under? How many are 11 and older? How many live in the state of Maryland? How many live outside the state of Maryland?

Record all the information below first as a fraction [11/20 for females would mean that 11 of the 20 people coming are female], then as a decimal [so 11/20 would = 0.55], then as a percent [11/20 = 55%]. Remember you can use keyboard shortcuts to copy the following and paste it into your answer. Then you just need to write the fractions, decimals and percents.

Males:

Females:

Brothers:

Sisters:

Parents:

Aunts:

Uncles:

Cousins:

Grandparents:

Friends of the family [FOF]:

Age 10 or under:

Age 11 or older:

Live in the state of Maryland:

Live outside the state of Maryland:

Bonus A:       

Add another category or two (or several) of your choice. Be creative [how many have x-box’s, iPads, been to Disney World – anything you can think of!]

Bonus B:

What is your highest fraction/decimal/percent? What is your lowest? What is the median fraction? What is the mean decimal? (Might want to use a calculator for that one.) What is the range of your fractions or decimals?
