Paired data in statistics, often referred to as ordered pairs, refers to two variables in the individuals of a population that are linked together in order to determine the correlation between them.

Facts and statistics collected together for reference or analysis are referred to as data. Data can be in the form of numbers, alphabets, special characters.

Paired samples (also called dependent samples) are samples in which natural or matched couplings occur. This generates a data set in which each data point in one sample is uniquely paired to a data point in the second sample.

There are generally three forms of presentation of data: ? Textual or Descriptive presentation ? Tabular presentation ? Diagrammatic presentation.

You have paired data when two variables are measured in the same person/unit each case/measurement. E.g. you can say you measured ten pairs of (armspan,height). If you wish to test ?X=a+?Y then you can also test ?X?Y=a which often is more precise since there is a smaller variance.

What are paired samples? Paired samples are samples to make inferences about the differences between two paired variables, such as the effect of one treatment on two behaviors. They can also help researchers estimate the amount of variation in one variable caused by variation in another variable.

Tabulation: Tables are devices for presenting data simply from masses of statistical data. Tabulation is the first step before data is used for analysis. Tabulation can be in form of Simple Tables or Frequency distribution table (i.e., data is split into convenient groups).

Paired samples compare the same population at different times or locations, while independent samples compare different populations. Knowing how to tell if a sample is paired or independent can help researchers make better decisions about their study designs and collect the most accurate data.

There're 5 solid and reliable data presentation methods: textual, statistical data presentation, measures of dispersion, tabular, and graphical data representation. Besides, some of the tested and proven charts for data presentation include: Double Bar Graph. Slope Chart.
