What is the proper format/syntax for the IF function?

information overload
A condition in which information inflow exceeds an individual's processing capacity How to Deal with Overload Filtering: Focus only on a specific task Sample information, don't read it all Modify or Distort new information to make it seem familiar Rely on Habit Oversimplify the complexity of information to make it easier to grasp Queuing by priority Develop Social Networks that do the filtering for you Withdrawal: disconnecting from sources of information (e.g., not checking email, turning off the TV, not surfing the Web)
Fact
A fact is a type of date. Its qualities include: a thing that is indisputably the case a piece of information used as evidence or as part of a report or news article. a statement that is consistent with objective reality or can be proven with evidence the usual test for a statement of fact is verifiability
vertical search engine
A website that indexes information on the World Wide Web in a specialized area. Examples: Amazon - Products Etsy - Crafts / Products Facebook Local - Businesses Houzz - Contractors Indeed - Jobs Pinterest - Everything Yelp - Businesses / Restaurants YouTube - Video Zillow - Real Estate
Meta search engine
All search engines have biases and "blind spots". A meta search engine searches multiple Search Databases Not all web sites are contained within a Search Engine Database Contains URLs plus some summary content; Ranks web pages by some criterion (keyword, popularity, payment) using an algorithm or formula; Users search the database, not the Web directly Spiders are a computer application whose purpose is to find content on the web Most search engine spiders look for relevant content that is organic (more when we get to SEO) They move around the web retrieving URLs or web page data, looking at content and meta tags (although meta tags have lost influence) They then place that information into the search database Example: Google's GoogleBot
Stakeholders in an Enterprise
Are Stakeholders: Partners/Suppliers Government Customers Employees Community Shareholders/Investors Are NOT Stakeholders: Competitors NonCustomers NonSuppliers NonInvestors NonPartners
evaluate information by "usefulness" and "believability"
Before taking the time to assess the believability of information, you should determine whether the information is useful for the task at hand. If the information is not useful, then there is no need to assess its believability. To determine whether information is useful, evaluate whether the information is relevant, appropriate, and sufficiently current. Each of these is a "go, no-go" assessment. At any point, if you evaluate the information as not passing the test, there is no need to go further. For example, if the information is not relevant, you do not need to determine whether it is appropriate or sufficiently current. Believable information is credible, objective, well supported, and comprehensive.
Primary Storage
Computer's main memory. Includes RAM (random access memory), ROM (read only memory), and CPU (central processing unit)
Synergy
Cooperative effort of complementary parts is greater than sum of those individual parts

Data converted into a meaningful and useful context Examples: Best selling product; best customer; worst selling product; worst customer
True/Useful Fact
Example: The sky is blue
False/Misleading Fact
False/Useless Example: The sky is above Misleading Example: The sky is green (when a storm is brewing)
Wittgenstein's "Form of Life" and "Language Games" useful in conducting a successful search
Form of Life The set of interpretations an individual has as a result of their profession or personal experience. On the Web/Internet, you need to learn the Form of Life surrounding an industry, an organization, a group of people. Example: Japanese accountants see a business differently from an American sales rep. Language Games The way people use words based on the situation. On the Web/Internet, you also need to learn how people involved in that Form of Life are playing Language Games. Example: You use words differently when you're talking with: your parent, a recruiter, your best friend.
Object code
Humans can NOT write, read, edit, delete it Computers can only run in this mode Companies become dependent on vendors for upgrades, fees, etc. Company doesn't have to deal w software development Source of revenue for vendors ex. Microsoft office, Oracle
Source code
Humans can write, read , edit, delete it Enables programmers to add custom features and capabilities Enable self-sufficiency for a company- don't have to rely on a vendor to make changes or fixes you need Not supported by vendors
representativeness heuristic
If an idea fits into an existing category well, then humans attribute the characteristics of that category to that new idea. Example: criminals have scary tattoos, that person has an scary tattoo, therefore that person is likely a criminal and I will view him/her as one.
availability heuristic
If something is easy to grasp and understand, then we tend to overestimate the likelihood of being true. Example: What is more likely to get you killed? terrorist, drowning, fire, road accident, homicide Rank: Road accident, homicide, drowning, fire, terrorism, natural disaster You are nearly 10 time more likely to die from "regular" homicide than terrorism. You are nearly 40 times more likely to die from a road accident than terrorism. Source: https://ourworldindata.org/causes-of-death

Know what these mean and which is bigger than the other: KB, MB, GB, TB, PB
Petabyte>Terabyte>Gigabyte>Megabyte>Kilobyte Kevin Might Get The Plug (smallest- largest)
3 main problems when evaluating information
Problem 1: Information Overload; The average person today processes more data in a single day than a person in the 1500s did in an entire lifetime. During the first day of a baby's life, the amount of data generated by humanity is equivalent to 70 times the information contained in the Library of Congress. Problem 2: More Variability in Info Quality; Argument 1: in the past professional editorial committees ensured that published information was high quality. Without these professional filters, information - in general - is lower quality because bloggers and others don't have the same professional skill or commitment to high quality information. Argument 2: in the past, professional editorial committees ensured that published information represented their view of the world, which ignored or misrepresented "the whole truth" of the world. Without these professional filters, bloggers and others can publish that "whole truth" from their perspectives. Problem 3: Information evaluation is hard; Humans evaluate information mostly automatically / subconsciously
What's the difference between a relative address and an absolute address? How do you make each in Excel?
Relative (will change when copy/pasted) and Absolute (won't change when copy/pasted) Cell References A1 - both column and row references are "relative" $A1 - the column reference is "absolute" but row reference is "relative" A$1 - Column reference is "relative" but row reference is "absolute" $A$1 - both column and row references are "absolute"
