Objectives of Data Summarization and Data Reduction Psychology Essay
In this article, we discuss summarizing data in Exploratory Data Analysis EDA. There are two main methods of summarizing data: numerical and visual. Numerical summaries use descriptive statistics to summarize the data. Descriptive statistics can help you understand the central tendency of the data, such as the mean, the. Data reduction techniques have emerged as preprocessing algorithms that simplify and clean raw data at an early stage while retaining as much information as possible. These techniques are used to both obtain a representative sample of the original data and alleviate data storage requirements. Only obtaining a,Data reduction refers to making the storage space required for,data more compact and improving its efficiency by summarizing,while reducing data complexity and preserving its built-in,characteristics. Its main purpose is the optimization of storage space, improving data processing speed and improving data for computational purposes,
