- Difference Between Discrete and Continuous Data
- Frequency Distribution of Discrete and Continuous Variables

Around this value, there is high concentration of the values. It is neither the central value nor the total sum of series which makes any effect on it. Every distribution cannot have a unique value of Mode. It can have two or even more than two modal values. The terms are arranged in any order.

The classification of data as a frequency distribution has an inherent shortcoming. While it summarises the raw data making it concise and comprehensible, it does not show the details that are found in raw data. There is a loss of information in classifying raw data though much is gained by summarising it as a classified data. Once the data are grouped into classes, an individual observation has no significance in further statistical calculations. For example : the class 20—30 contains 6 obervations : 25, 25, 20, 22, 25 and So when these data are grouped as a class 20—30 in the frequency distribution,the latter provides only the number of records in that class i.

We shall continue our discussion on frequency distributions in this article by moving on to Frequency Distributions of Discrete and Continuous Variables. Table No. For a continuous variable if we take a class for each distinct value of the variable, the number of classes will become unduly large, thus defeating the purpose of tabulation. In fact, since a continuous variable can assume an infinite number of values within its range of variation, the classification or sub-division of such data is necessarily artificial. Some guidelines that should be followed while dividing continuous data into classes are as follows:. Let us consider the following example regarding daily maximum temperatures in in a city for 50 days. Class Interval: The whole range of variable values is classified in some groups in the form of intervals.

For eg: \\(1,2,3,4,5,6,7,8\\\) is an Individual Series. Discrete Series: Discrete Series is a statistical series in which all the observations are listed out along with.

Sign in. Data Types are an important concept of statistics, which needs to be understood, to correctly apply statistical measurements to your data and therefore to correctly conclude certain assumptions about it. This blog post will introduce you to the different data types you need to know, to do proper exploratory data analysis EDA , which is one of the most underestimated parts of a machine learning project.

The similarity is that both of them are the two types of quantitative data also called numerical data. However, in practice, many data mining and statistical decisions depend on whether the basic data is discrete or continuous. If you have quantitative data, like a number of workers in a company, could you divide every one of the workers into 2 parts? The answer is absolutely NOT.
