Now that you know how to distinguish between the different types of data, you are ready to collect data for your project in Six Sigma measure phase. The rating scale of 1 represents “Strongly Dislike,” the scale of 2 represents “Dislike,” The scale of 3 represents “Neutral,” the scale of 4 represents “Like, ” and the rating of 5 represents “Strongly Like.” In this case, a rating of 5 indicates more liking or enjoyment than the rating of 4. Discrete numeric data is countable in the sense that you can count how many of something there are. Continuous Variables. Organize distributions of data by using a number of different methods. Understanding the difference between continuous and discrete data is important because the difference influences how Six Sigma project teams define their measures, how they collect their data, and what they can learn from it. This type of data is, The third type is discrete binary data. Discrete data is also known as attribute data. The “X” or “Y” data in Six Sigma methodology can be either continuous data or discrete data. Moreover, the data, related to gender, race, religious affiliation, political affiliation, etc., are also nominal data. Please remember a fundamental rule about types of data here. Discrete data key characteristics: You can count the data. The basic types of data. Even some reputable, will cover different types of data when discussing the Six Sigma Measure phase of the, process. The difference also affects the sampling of data and how they will analyze it too. How to Distinguish The Different Data Types of Six Sigma Measure Phase? In other words, continuous and discrete are two different data types often used in Six Sigma measure phase. “This type of data is typically used when collecting behavioral data (for example, user actions on a website) and thus is a true representation of actions over time. It stands to reason that the people who study in a, will be confronted with different data types in Six Sigma measure phase. Nominal data can also be equated to discrete values, for example, to distinguish among people such as sales representatives, marketing representatives, etc. It can take any value in some interval. Continuous Data can take on any value on a continuous scale such as temperature, distance, cycle time, profit. Continuous data is information that can be measured at infinite points. Nominal data is not applicable to be measured against the time of the day. For example, the mean height in the U.S. is 5 feet 9 inches for men and 5 feet 4 inches for women. For example, taking the average temperatures for each month during a year is an example of continuous data. Have a look at the figure below. You cannot measure the data.

Nature: Countable: Measurable: Values: It can take only distinct or separate values. Continuous variables represent measurable amounts (e.g. Knowledge of different data types of Six Simga measure phase is essential for the Six Sigma practitioner. Discrete numeric data is measured by the presence or absence of a particular characteristic of each device that is being tested during Six Sigma measure phase. For example, “The third tallest person in the class” (We don’t know how tall, only that there are two others taller than this person). Count of errors or number of errors on a bill, Discrete attribute data of Six Sigma Measure Phase. Graphical Representation: Bar Graph: Histogram: Tabulation is known as Discrete data is also known as attribute data. Let’s take a closer look at what discrete data means for Six Sigma measure phase. The data types that he or she will be confronted with during the Six Sigma measure phase of a project will, 5 Positions Which Must Be in a Six Sigma Team, Six Sigma Certification Cost: Learn the Two Main Aspects of 6σ Cost, free Six Sigma Green Belt Certification training, https://www.youtube.com/watch?v=AHJ6KpqdOmU, https://www.youtube.com/watch?v=xEQKpzrlDqs. Knowledge of different data types of Six Simga measure phase is essential for the Six Sigma practitioner. the number of objects in a collection). By nature, discrete data cannot be … Let take a simple example. The second type is discrete nominal Data. In the Six Sigma measure phase of the DMAIC process, before doing actual data collection, the project team should consider some statistical techniques including types of data and sampling. Continuous data is one that falls on a continuous sequence. A set of data is said to be ordinal if the values/observations belonging to it can be ranked or put in order or have a rating scale attached. Converting Types of Data. Data comes in a number of different types, which determine what kinds of mapping can be used for them.
