Other terms that can be used to describe the concept are arithmetic mean, average and mathematical expectation. 1. Statistics is also the mathematical study of the likelihood and probability of events occurring based on known quantitative data or a collection of data. The term "average" is used a lot with data sets. The data are essentially organized to a certain model that helps to process the needed information. can be Discrete or Continuous: Put simply: Discrete data is counted, Continuous data is measured, To help you remember think "Quantitative is Quantity". A Sample is when we collect data just for selected members of the group. In this teacher guide, you can learn the importance of utilizing data analysis with your students and strategies for teaching students how to conduct data analysis. longer. n. 1. Data can be analyzed using a number of ways like Tally marks, Pie graphs, Bar charts, Line graphs, Line plots, Histogram, Frequency tables, measures of central tendency and many more. That is a sample. Data can be collected from sources or through observation, surveys, or by doing experiments. Together with range, they help describe the data. Statistical data synonyms, Statistical data pronunciation, Statistical data translation, English dictionary definition of Statistical data.
