Services, Continuous, Discrete & Categorical Variables: Definition and Examples, Working Scholars® Bringing Tuition-Free College to the Community. As a result the probability that the random variable would take on any particular one of these infinite values is said to be zero. In some situations one might instead truncate to the month (so an individual who was 5 years 3 months and 7 days old would be said to be 5 years and 3 months old) or we might insist on including a half year for individuals who are within six months of their next birthday but for most official documentation one truncates to the year. Under this method ##5## ##5.1## ##5.01## ##5.0000000000000000001## etc would all be distinct ages. Age is commonly measured in years, which would make it a discrete variable. Fill in the blank space, and explain. Height of a person; Age of a person; Profit earned by the company. Sciences, Culinary Arts and Personal Age is generally given in years, at least in humans. © 2019 Essay Conect. 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. ☑Exceptional grades A discrete variable is a variable that can only take certain values and is therefore easily countable. Earn Transferable Credit & Get your Degree, Get access to this video and our entire Q&A library. ##Y## could be 9 or 42 or 75 but it couldn’t be 75.5 for example. Create your account. ☑100 % original papers Continuous Variable. We would have an infinite number of values within a finite range. ☑24/7 availability of writers. - Definition & Examples, Continuous Data Set: Definition & Examples, Factor Analysis: Confirmatory & Exploratory, Issues in Probability & Non-Probability Sampling, Intervening Variable: Definition & Example, Univariate Data: Definition, Analysis & Examples, Statistical Analysis for Psychology: Descriptive & Inferential Statistics, What is a Chi-Square Test?

Become a Study.com member to unlock this In such a case ##Y## representing the age of an individual in years could take on a finite number of values within our range. As an example suppose that the random variable X representing your exact age in years could take on any value between 0 and 122.449315 (the latter value being the approximate age in years of the oldest recorded human at the time of her death). By and large, both discrete and continuous variable can be qualitative and quantitative. Key Differences Between Discrete and Continuous Data. (However one could determine the probability of the variable taking on a value less than or greater than a given reference value). It is correct to consider age as a continuous variable, but we collect data on people's ages as if they were discrete variables. answer! Height is an example of a continuous variable - someone could be 1.834215m tall. The data distribution for this random variable would be discrete. As an example suppose that the random variable X representing your exact age in years could take on any value between 0 and 122.449315 (the latter value being the approximate age in years of the oldest recorded … If a data set is continuous , then the associated random ... socratic.org Statistics: Power from Data! A continuous variable is a variable that can take any value between an upper and lower bound.

Conclusion. If a data set is continuous then the associated random variable could take on any value within the range. For Example, Age, height or weight of a person, time taken to complete a task, temperature, time, money, etc. Answer: Continuous if looking for exact age discrete if going by number of years. Age is commonly measured in years, which would make it a discrete variable. All Rights Reserved. ☑ Timely Papers Answer: Continuous if looking for exact age, discrete if going by number of years. Typically however age is truncated; a person who is ##5.1## years old and a person who is ##5.6## years old would both be said to be ##5## years old.
