You can ask everyone (all 120) what their age is. The singular form is "datum", so we say "that datum is very high". Quantitative data is defined as the value of data in the form of counts or numbers where each data-set has an unique numerical value associated with it. "Data" is the plural so we say "the data are available", but data is also a collection of facts, so "the data is available" is fine too. The value of r is always between +1 and –1. Data can be collected from sources or through observation, surveys, or by doing experiments. millimeter (mm) pound.

The mean (or average) of a set of data values is the sum of all of the data values divided by the number of data values. 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. n. 1.

Mathematics (from Greek: μάθημα, máthēma, 'knowledge, study, learning') includes the study of such topics as quantity (number theory), structure (), space (), and change (mathematical analysis). The set of data is any permanently saved collection of information which usually contains either case-level, gathered data, or statistical guidance level data. To interpret its value, see which of the following values your correlation r is closest to: Exactly –1. There are many useful properties of sets of data that are used in basic mathematical analysis, including the range. What is data labeling used for? Measurements >.
