Math for Journalist

1) A local college releases figures showing that its total budget is $120 million. Of that total, $80 million comes from the state, $6 million from student tuition, and the remaining $34 million from fees, grants and gifts.

It gets 67% of this figure from the state, which is its most significant source. The least significant source is the 5% that comes from the student tuition. The rest of the funding comes from fees, grants, and gifts, which amounts to 28% of the total budget.

2) Your editor assigns you to do a story about prison sentences handed down in cases of aggravated assault. He gives you the following figures from an anti-crime group that is lobbying for tougher sentencing guidelines. The cases represent the people convicted for aggravated assault in San Jose in one month in 2006.


*
22 months is the average prison term for the seven people listed below.

* 12 months is the median for the seven people listed below. In this case the median is a more accurate description of prison terms because of Michael Reese had a term of 7 years which was more than the other 6 terms combined. His term would be considered an outlier that would skew data if set in a graph. He makes the average term 22 months or a 1 year and 10 months, which if looking at the data set one could see that no one but Reese, served more than a 1 year and 2 months.

Name Sentence
Donald Lee 1 year prison, 2 years probation
Richard Smith 1 year prison, 1 year probation
Wesley Mitchell 14 months prison, 1 year probation
Mary Jones 1 year prison, 1 year probation
Juan Rodriguez 1 year prison, 2 years probation
Harold Rothstein 8 months prison, 1 year probation
Michael Reese 7 years prison, 5 years probation

3) The state legislature is considering exempting restaurant food sales from the sales tax in the same way grocery sales are exempt.

State tax sales- 7.25%

Fast food-52 weeks in a year – $260 spent without sales tax. They would save $18.85 a year.

More expensive meal- 52 weeks in a year- $1040 spent without sales tax. They would save $75.40 a year.

1) Your numbers are correct, but make your explanation more conversational. For example, you probably wouldn't say 67 percent (and when you write it, you need to write out "percent," by the way). Instead, you'd probably say that two-thirds of the college's budget comes from the state, and more than a quarter of the funding comes from fees, grants, and gifts, etc.

2) Got it!
3) Got it!
