A person's age does, after all, have a meaningful zero point (birth) and is continuous if you measure it precisely enough. If a data set is continuous, then the associated random variable could take on any value within the range. Actually, there are more types that categorical and continuous. Conclusion. Data can be Descriptive (like "high" or "fast") or Numerical (numbers). Generally, age is specified as a count of the number of full years lived, but it is used as a continuous variables.

In addition, continuous data can take place in many different kinds of hypothesis checks. QUESTION 22 1. A discrete variable is a variable that can only take certain values and is therefore easily countable. Continuous random variables have numeric values that can be any number in an interval. Continuous or Discrete? ). Treating a predictor as a continuous variable implies that a simple linear or polynomial function can adequately describe the relationship between the response and the predictor. Height is an example of a continuous variable - someone could be 1.834215m tall. Wait! Systolic blood pressure is continuous variable having values in the range 80 to 160 mm of mercury. Continuous.

By and large, both discrete and continuous variable can be qualitative and quantitative. As a result the probability of the random variable taking on any of these finite discrete values within our range could be non-zero. And we do not often think of dividing a dog or house into parts, e.g. A discrete distribution means that X can assume one of a countable (usually finite) number of values, while a continuous distribution means that X can assume one of an infinite (uncountable) number of different values. Discrete and Continuous Data. continuous. 1. Age is generally given in years, at least in humans.

Discrete time views values of variables as occurring at distinct, separate "points in time", or equivalently as being unchanged throughout each non-zero region of time ("time period")—that is, time is viewed as a discrete variable.Thus a non-time variable jumps from one value to another as time moves from one time period to the next. It is meaningful to … Age is either discrete (a count) or continuous depending on how age is measured. OP you are both wrong age is neither count nor continuous in your sense, it is a duration, you should be fitting survival models, try Cox proportional hazards. 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. This will certainly affect how it is measured as well. How you study this data should differ based on which group it falls into. Most physicists honor Einstein’s insight, and so most approaches to quantum gravity take space and time to either both be continuous or both be discrete.
