Going left to right in the picture below, notice the data is more informative.Īlso notice the performance seems to be worsening over time and is Performance of each shipment compared to its target delivery time can beĬalculated in days or possibly even hours. And each shipment has an actual arrival time. Very Early, Early, On-Time, Late, or Very Late.Įach shipment should have a due date and possibly a specific time. This provides a little more data but still not ideal. Or groups such as Shipment as arriving 0-1 days early, 2-3 days early, 0-1 days late, 2-3 days Instead of recording whether students PASS or FAILED the SAT, it would be better to have each student's actual score on the SAT.Įxample Two: Instead of a A Six Sigma Black Belt is looking to collect data on the timelinessĮach shipment as being late or on time (which is a binomialĭiscrete data). Continuous data often more time consuming to obtain.Ĭonvert to continuous data when possible as shown in the table below are a few examples to obtain a higher level of information and detail:.Continuous data can remove estimation and rounding of measurements.Continuous data provides more informative than discrete data.Continuous data is more precise than discrete data.This is the lowest level of data type due to low level of information provided. Discrete often refers to a "count" but may able related to an "attribute" characteristic.Ī binomial measurement is the type of attribute measurement that has two characteristics. More about Attribute Data: Used to represent the presence or lack of a certain characteristic. political party affiliation (considered discrete categorical data)īar graphs, pie charts, and Stem-and-Leaf plots are good choices for discrete data.# of defects on an order form or in a batch of parts.race (considered discrete categorical data).gender (considered discrete categorical data). ![]() ratings provided on an FMEA for Severity, Occurrence, and Detection.rating 1-10 (whole numbers with 1 being LOWEST - 10 being HIGHEST).Attribute and discrete do not mean exactly the same when describing data, discrete has more than two outcomes. It is either 129 or 130, in this case you would round down to 129. Example: How many people can comfortably fit into an airplane? It does not make sense to say 129.7632213 people. The count value can not be divided further on an infinite scale with meaning. Data that can be sorted into distinct, countable, and in completely separate categories. Examples are:ĭiscrete (Attribute) Data: Data types that have a finite number of measurements and are based on counts. These variables generally represent things that are measured, NOT counted. to 0.999999999999.) The continuous random variables can be any of the infinite number of values over a given interval. Even if the measurements range from 0-1 there may be an infinite number of measurements within (0.000000000000. It is data that can be expressed on an infinitely divisible scale. There are no limits to the gaps between the measurements. Theoretically has an infinite number of measurements depending on the resolution of the measurement system.
