Simple way to think about this: you, me, and your best friend need to split $10, in the form of a 10 dollar bill. That could never be true of a continuous variable. I've collected prices (from rightmove.co.uk estate agents) for 4 Bedroom houses for sale and to let (price per month) and 2 bedroom flats for sale and to let (price per month) For both an area in London and an area in Newcastle. So, does anyone know what sort of data this is? The difference between discrete and continuous data can be drawn clearly on the following grounds: Discrete data is the type of data that has clear spaces between values. Discrete Data. However, money is continuous because it can have many and any value and be of any amount, considerably. Continuous data is data that falls in a continuous sequence. The data is discrete since it is based on a monetary system. Discrete "If a variable can take on any value between two specified values, it is called a continuous variable; otherwise, it is called a discrete variable." I'm doing statistics coursework and I can\t work out what the data I've collected is. Join Yahoo Answers and get 100 points today. Find its width.? You will GROUP the data into values like £100,000 - £199,999, etc...so the data becomes discrete but grouped... Higher level graph could be a cumulative frequency graphs and compare the two cities using box plots...look for bias in the plots... You will have four graphs...make sure you do the 2 bed for both cities on the same sheet (to compare) and the 4 bed houses for each city on a second sheet (again to compare). Discrete numbers are like stepping stones, continuous numbers are like a sidewalk. With stepping stones you are either on the 1st stone, or the second stone but it is impossible to be anywhere in between. So according to that above definition, it is not continuous. The number of books purchased would be a discrete variable. Join Yahoo Answers and get 100 points today. A discrete variable can be graphically represented by isolated points. If the area of a rectangular yard is 140 square feet and its length is 20 feet. Discrete and Continuous Data. Discrete Data can only take certain values. I maintain that cost is discrete. For example, would "The actual cost of a student's textbooks for a given semester" represent discrete variables or continuous variables? For example, suppose that the cost of producing a car is 20000 dollars. For example, to evaluate the accuracy of the weight printed on the product box. Nowhere is it written that discrete variables only take integral values. Surgeon general: What to do if you had an unsafe holiday, Report: Sean Connery's cause of death revealed, Padres outfielder sues strip club over stabbing, Biden twists ankle playing with dog, visits doctor, Mysterious metal monolith in Utah desert vanishes, Virus-depleted Broncos have historically bad day, Jolie becomes trending topic after dad's pro-Trump rant, How Biden's plans could affect retirement finances, Doctor's office probed in wake of Maradona's death, Judges uphold Kentucky governor's school order, Reynolds, Lively donate $500K to charity supporting homeless. The cost of a student's textbooks would be a continuous variable because it can take on any measured value--with a decimal point. So according to that above definition, it is not continuous. In addition, continuous data can take place in many different kinds of hypothesis checks. Can science prove things that aren't repeatable? The table below shows the costs of producing 1, 2, 3, or 4 cars. For example, you will never find a house whose price end in a 1/2 cent, or .33333 cents etc. This situation will give discrete data only since you cannot produce half of a car, three-fourths of a car or two and a half car. My hypothesis is that houses in London are more expensive then houses in Newcastle. If the area of a rectangular yard is 140 square feet and its length is 20 feet. Get answers by asking now. Still have questions? Discrete data is countable while continuous data is measurable. For example, you will never find a house whose price end in a 1/2 cent, or .33333 cents etc. Data can be Descriptive (like "high" or "fast") or Numerical (numbers). Alternatively if you use cents as the unit of cost, then cost can only take integral values. "If a variable can take on any value between two specified values, it is called a continuous variable; otherwise, it is called a discrete variable.". The data is discrete since it is based on a monetary system. Find its width.? And what higher level graph (according to AQA GCSE specification) would be appropriate to represent the data? Well, we first notice that a SINGLE 10 dollar bill isn’t at all divisible if the money is to keep its value. Can science prove things that aren't repeatable. Discrete variable assumes independent values whereas continuous variable assumes any value in a given range or continuum. Between $10.99 and $11.00, there is no valid value for cost, so cost cannot take values between those two specified values. Example: the number of students in a class. And Numerical Data can be Discrete or Continuous: Discrete data is counted, Continuous data is measured . Discrete data contains distinct or separate values. For discrete data, numbers between two data values will make no sense. Which of the following line integrals is independent of path. Still have questions? In comparison to discrete data, continuous data give a much better sense of the variation that is present. Unlike, a continuous variable which can be indicated on the graph with the help of connected points. For example, pay, whereas it can have an infinite value. Get your answers by asking now. Between $10.99 and $11.00, there is no valid value for cost, so cost cannot take values between those two specified values.
