The second part, "series," is pronounced as "seer-eez" with a long "e" sound in the first syllable, and a long "i" sound in the second syllable.

A data series refers to a collection or sequence of data points or values that are organized and presented in a specific order. It consists of a set of data that is usually related to a specific variable or phenomenon, gathered and recorded over a period of time or across different categories. These data points can be numeric, qualitative, or categorical in nature, representing measurements, observations, or characteristics of a particular subject.
Typically, a data series is represented in a tabular format, with each data point occupying a separate row or column. The series can be arranged in ascending or descending order, often depending on the key variables being analyzed. The organization of the data series can help identify trends, patterns, or relationships within the dataset, making it a vital tool for statistical analysis, research, and data visualization.
Furthermore, data series play a crucial role in various fields, including economics, finance, science, and social studies. In finance, for example, a stock price data series may depict the daily closing prices of a particular security over a specific period. In scientific research, a data series might consist of measurements taken at regular intervals during an experiment, allowing researchers to analyze and interpret the results accurately.
Overall, a data series represents a structured and sequential collection of data points, enabling researchers, analysts, and scientists to gain insights and draw conclusions about the underlying variables or phenomena being studied.
