To check which datasets are included in Data Planet Statistical Datasets, or to see if your institution subscribes to any premium datasets, go into Statistical Datasets and look at the Indicator column along the left. If you subscribe, you'll see the premium datasets listed, along with all available datasets in the indicator tree on the left-hand side of the screen.
Datasets and indicators may be browsed by broad subject category and by source.
For a full listing of datasets available in Data Planet Statistical Datasets, and the sources of these datasets, see Data Planet Datasets and Sources.
Below you will find simple definitions of the basic terminology associated with data and statistics. The examples will link into DataSheets from Data Planet Statistical Ready Reference. From the DataSheets, you can link into Data Planet Statistical Datasets to explore the millions of datasets available in the repository.
Data Planet publishes aggregated secondary datasets:
Secondary means that the data are collected by source organizations other than Data Planet. Secondary data are contrasted with primary datasets, which refer to data that researchers have collected themselves.
Aggregated means simply that the datasets are a collection of summary data, vs microdata, which refer to the individual response items in surveys and other data collection instruments.
Data: Fundamentally, data=information. We typically use the term to refer to numeric files that are created and organized for analysis. There are two types of data: aggregate and microdata.
Data point or datum: Singular of data. Refers to a single point of data. Example: the amount of aviation gasoline consumed by the transportation sector in the US in 2012
Quantitative data/variables: Information that can be handled numerically. Example: spending by US consumers on personal care products and services
Qualitative data/variables: Information that refers to the quality of something. Ethnographic research, participant observation, open-ended interviews, etc., may collect qualitative data. However, often there is some element of the results obtained via qualitative research that can be handled numerically, eg, how many observations, number of interviews conducted, etc. Example: periods when the US was in, vs was not in, a recession, 1850-2014 The quality of being in a recession is assigned a value of .01 and not in a recession .0, which makes it possible to display as a chart.
Indicator: Typically used as a synonym for statistics that describe something about the socioeconomic environment of a society, eg, per capita income, unemployment rate, median years of education.
Statistic: A number that describes some characteristic, or status, of a variable, eg, a count or a percentage. Example: total nonfarm job starts in August 2014
Statistics: Numerical summaries of data that has been analyzed in some way. Example: ranking of airlines by percentage of flights arriving on-time into Huntsville International Airport in Alabama in 2013
Time series data: Any data arranged in chronological order. Example: Gross Domestic Product of Greece, 2000-2013
Variable: Any finding that can change or vary. Examples include anything that can be measured, such as the number of logging operations in Alabama.
Terminology Used with Collections of Data
Data aggregation: A collection of datapoints and datasets. Example: a search on the broad category "energy resources and industries" retrieves results from multiple sources
Dataset: A collection of related data items, eg, the responses of survey participants. This term is used very loosely – the entire Census 2010 Summary File 1 can be considered a dataset as can any individual table published in the Census 2010 Summary File 1, eg, Table P20. Households by Presence of People Under 18 Years by Household Type by Age of People Under 18 Years
Time series: A set of measures of a single variable recorded over a period of time. Example: Hourly Mean Earnings of Civilian Workers – Mining Management, Professional, and Related Workers
"Big Data" Terminology
Big data: A popular term used to describe the exponential growth and availability of structured and unstructured data that derived from the increasing sophistication of operational and transactional systems, mobile media, and the Internet. Big data and its analysis have become key components of obtaining business intelligence in particular.
Data analytics: Generally used to refer to the analytical techniques and tools required to analyze massive amounts of data. Closely related to data mining, which refers to the extraction of information from business systems.
