Math

• Exponents A power is a way of showing repeated multiplication
• Exponents

  A power consists of a base and exponent, the bases is the number you multiply.
• 3^5 the exponent how many times you multiply the number

  Example: 3x3x3x3x3
• when you multiply two numbers with the same, base, you add the exponents together example: 2^5 x 2^4 = 2^(5+4)=2^9
• when you divide two numbers with the Same base. you Subtract the exponents from each other example: 2^5 ÷ 2^3 = 2^(5-3)= 2^2
• when you have an exponent raised to another exponent you multiply the exponents example: (3^2)³= 3^(2 x 3) = 3^6
• Remember: BEDMAS

  Brackets exponents divide multiply

  add Subtract
• Surveys Survey questions Should be worded so they are free from factors that may result in Influencing factors causing an influenced decision
• Bias:

  this means we need to be careful to ask questions in a way that doesn't make people feed like they have to answer a certain way. honest answers/ responses are what we want example/tip: avoid giving your personal opinion
• Languages:

  We need to make sure the questions don't use offensive terms and use simple enough terms most people should know
• ethics:

  we have to be fair and honest when collecting data, making sure not to challenge, someone's morals and make sure not to make people uncomfortable.
• Cost: Sometimes it costs money to run a survey or to even partake in a survey so we must take that into account when collecting data
• Time : it takes time to ask people questions so we must make sure we have enough time to get accurate results. when doing/creating a Survey
• Privacy: when doing a survey we must hees every one's answers private from the public when answering to ensure Safety and honesty
• Cultural sensitivity:

  We need to make sure the languages and questions we use are respectful to all cultures and

  makes sure not to offend anyone
• Collecting Data/ways to collect data population:

  a population, all of the people the Survey is about and may affect or in a designated area

  Samples: a Sample is a smaller group of the population as a Substitute instead of a population
• Convenience: a Sample of the population asked the questions to the survey due to their timing or convenience
• voluntary: a sample of the population asked the questions to the Survey due to their will to do the survey, So they get to choice if they'd like to participate or not
• Random: a Sample of the population asked the questions to the Survey decided by a random way still giving everyone a fair chance though example: random generator or names in a hat
• Stratified: a Sample of the population divided into groups like; boys and girls and then ask an equal percentage of each group
• Systematic: this is a sample of the population asked the survey question at fixed intervals from a list of the population example : every 5th person in a line
• on linear graphs you can interpolate values in between the known values, remember Interpolate has the word "IN" meaning its withIN the known values
• on linear graphs you can extrapolate values beyond the known values, remember EXTRApolate has the word extra" meaning it's extra values beyond the known values
• you can graph linear relations using an equations, use the equation to make a table of values and graph the coordinate pairs and it'll form a straight line

  Also known as a linear graph
