Equation terms

Standard deviation – The standard deviation is the measurement for how spread out your data is and is shown with a σ symbol

Null hypothesis – The idea that you are trying to prove wrong eg. That too much of your budget is going on coffee.

Alternative hypothesis – The idea that you are trying to prove right eg. The goverment is taking too much money from your budget.

More venn diagrams

Cartisan product – The two amounts of elements multiplied

Cardinality – How many elements in a set

Power set – All the combinations of a subset including 0

Trick for finding all the numbers in a venn diagram

If you know the combined eg. all three option put it in first

Venn diagram equations

∩ = And or Λ

υ = Or or V

– = not or ¬

Intersection – Where two circles connect and make another section

Union – All the numbers within the circles

Complement – The area outside of the circles but inside the box, specifically the numbers in this area

Disjoint – When the circles do not intersect

Power sets

If A = {1, {1}, {2}, 3}

The elements are each of the items within the outside brackets eg. 1, {1}, {2}, 3

The subset is the format of each item of a set eg. {1},{{1}}, {{2}}, {3}

Sets and relations

Sets

Any defined collection of items with something in common

Relationship

A relationship is how items of a set relate to each other. Most often used to define a subset within a group

Language of sets

If the set has only a few members you can write all the elements between curly brackets eg. P = {Peter, John, Paul}

If there is a clear pattern you can use three eclipses (dots) eg. S = {2, 4, 6, 8…}

N = Natural numbers

W = Whole numbers

J = Intergers

Q = Rational numbers

R = Real numbers

Subsets

Subsets are equal to their sets, so A=B and B=A

Odds and ratios

Number of out comes/Size of sample space (number of options)

eg. Rolling a dice

1/6 = Odds of getting any number

3/6 = Odds of getting either an odd or even number

Mutually exclusive – Independant events

Complimentry

If the dice is a complimentry of six…

The odds of getting 4 are 1/6 so the odds of not getting a 4 are 5/6

1/6 5/6 Both top numbers = the bottom number

Similarities and differences in the negotiation process between The Netherlands and Chile

The Netherlands

General

They speak neither loudly nor quietly

Silence does not mean they are conveying a negative message

‘Saving face’ is not an important part of this culture, they would rather be honest and are rather blunt.

Rather than giving a round about answer instead of no it is better to give no answer.

Eye contact is used intensely and convey’s sincerety and build trust

Personal life is not discussed in business

They are not particularly fond of haggling but can be good at it.

Prices rarely move more than 20-30% between initial and final offers

Arguments should be based on hard facts

Lying is used only occasinally

The good cop, bad cop method may work in negotiation

Corruption and bribery are rare

When in other countries they make decisions faster and usually have the authority to ‘seal the deal’

They use universal techniques when making decisions and don’t like making exceptions

Oral agreements are usually dependable but written contracts are better

Women have similar rights as men although they struggle a little to attain the same postions as men

Chile

General

People usually speak softly

‘Saving face’ is important in this culture, honor and pride play a big part in business

Constant eye contact conveys sincerety and builds trust

It is better to negotiate in teams rather than with just one person

Meetings may start with small talk which may include personal questions about family and background

Don’t like like bargaining and hate haggling

More likely to find power and status more appealing than money

Lying is used only occasionally

‘Good cop, bad cop’ approach may work

May use emotional techniques such as making you feel guilty or using your personal relationships as leverage

Corruption and bribery are rare

More likely the consider the indivdual situation rather than using universal principals

Oral agreements are not usually dependable

Woman may still be considered inferior in the work place

Negotiation styles

The dutch use a monocronic work style and may show little tolerence toward a polycronic style

Chilians prefer a polycronic work style

Monocronic is when items to be discussed are worked out in an order, polycronic is when items are discussed in a random order and points are jumped between.

Taxes

Netherlands

The 30% rule

This is where 30% of your pay is not taxed for up to 120 months if you are working abroad in the country and the company you are working for is based in the Netherlands.

Maths stats assignment

For the assignment I intend to use ravelry to find out how long people have been knitting and how long they have been members of ravelry also possibly their ages.

I could do this with or without a questionaire as the information is provided in profiles on the website, I will be asking for volunteers for it either way.

I have also thought about doing a knitting vs crochet questionaire but I’m not sure whether I will need to or not.
