6 Data: Collection of facts (opinions, demographics, statistics) Information: A message received and understood * A collection of facts from which conclusions may be drawn

7 Data: Collection of facts (opinions, demographics, statistics) Information: A message received and understood A collection of facts from which conclusions may be drawn * Knowledge acquired through study, or experience, or instruction

8 Data: Collection of facts (opinions, demographics, statistics) Information: A message received and understood A collection of facts from which conclusions may be drawn Knowledge acquired through study, or experience, or instruction * Information as the result of processing, manipulating and organizing data in a way that adds to the knowledge of the person receiving it.

9 Information: Something that changes what you know.

10 Suppose you received these reports:

11 Suppose you already knew everything in these reports:

12 Would you still want to pay for these reports?

13 Information: Something that changes what you know.

14 Information: It is a commodity.

15 Information: It is a commodity. It is property.

17 Information: 1. Value Dependent upon the value of decisions that can be made with a change in what you know.

18 Information: 1. Value Dependent upon the value of decisions that can be made with a change in what you know. Value = Benefit - Costs

19 In a business sense the value of information could be Negative.

20 Information: 1. Value 2. Amount Not dependent upon length or complexity

21 Information: 1. Value 2. Amount Not dependent upon length or complexity Amount is inversely proportional to the probability of the message

29 The print media stays in business by selling advertisements and influence Because…. People will be attracted to the media when they find something that they didn’t already know.

30 In other words… people are attracted to and buy Information Even if it is wrong!

50 Information: Evaluation Who produced it? When was it produced? How was it produced? How was it analyzed? Why was it produced? Who benefits from this information?

51 Information: Evaluation Who produced it? When was it produced? How was it produced? How was it analyzed? Why was it produced? Who benefits from this information? Why is this information available to me?

73 What we know about climate change and drought http://www.washingtonpost.com/blogs/wonkblog/wp/2012/07/24/what-we-know-about- climate-change-and-drought/ “And the short version is this: Droughts have multiple causes. The United States has suffered worse droughts in the past. It’s not yet clear whether we’ve reached the point where global warming is making droughts worse again, at least in North America. But evidence suggests that droughts will become more intense in many parts of the world if the planet keeps heating up — a trend that could disrupt the world’s food supply.” Link between global warming and drought questioned http://www.newscientist.com/article/mg21628914.600-link-between-global-warming- and-drought-questioned.html “Roger Pielke Jr. of the University of Colorado in Boulder says that since the PDSI uses a formula that assumes higher temperatures cause more droughts, it was hardly surprising that it finds a link.”
