Definitions of Frequency distribution on the Web: The organization of data to show how often certain values or ranges of values occur. biz.yahoo.com/glossary/bfglosf.html A complete summary of the frequencies of the values or categories of a variable; often displayed in a two column table: the left column lists the individual values or categories, the right column indicates the number of observations in each category. www.cdc.gov/nccdphp/drh/epi_gloss.htm A frequency distribution shows the number of observations falling into each of several ranges of values. Frequency distributions are portrayed as frequency tables, histograms or polygons. www.cirem.org.uk/definitions.html A distribution in which the values of the dependent variable are tabled or plotted against their frequency of occurrence. www.uvm.edu/~dhowell/StatPages/Fundamentals/Glossary.html A tabulation of the number of occurrences of individual elements in a body of text or key. www.nsa.gov/programs/kids/glossary.shtml The proportion of the target audience that will see the publications in the schedule a certain number of times. eg. 3 or more times (3+). newsmedianet.com.au/home/Glossary.jsp A frequency distribution is a systematic way to order a set of data from lowest to highest value showing the number of occurrences (frequency) at each value or range of values. www.brendan.com/Glossary.htm A means of summarizing the phenotypes of a continuous trait whereby the population is described in terms of the proportion of individuals that have each phenotype. www.modernhumanorigins.com/f.html The classification of numerical data according to size or magnitude. A population whose elements are classified according to some quantitative characteristic (dollar value, of purchase orders, or of invoices, etc.) may be described by a frequency distribution. A symmetrical distribution is a frequency distribution that can be portrayed by a normal (bell) curve. A skewed distribution is a frequency distribution which extends further in one direction than in another. An example of a skewed distribution would be one that involved 500 sales invoices totaling \$1,000,000 with 5 of the invoices amounting to \$100,000 each. By examining all of the high value invoices and thereby removing them from the skewed distribution, the remaining invoices, assuming no further extremes, would reflect a normal distribution lending itself to random sampling. www.window.state.tx.us/taxinfo/audit/sampling/glossary.htm A table that graphically presents a large volume of data so the central tendency (such as the average or mean) and distribution are clearly displayed. www.asq.org/info/glossary/f.html In SPSS (and other statistical packages) a frequency distribution shows how often a given value occurred. For example a frequency distribution of the variable gender for a sample of 100 people, half of whom were men and half women would show Men: 50; Women: 50. bss.sfsu.edu/legates/Analyzing/analyzing_glossary.htm A display of cases divided into mutually exclusive and contiguous groups according to a quality-related criterion. www.qualitymeasures.ahrq.gov/resources/glossary.aspx A report of the number and type of responses to a particular question, e.g. the following is a frequency distribution for an income variable www.saurageresearch.com/glossary.html A listing of scores and the number of persons receiving each score. fc1.tamu.edu/home/keycomponents/glossary.html a graph depicting the number of times each score appears in the data set. www.cwu.edu/~millerj/stathelp/definitions.html A statistical table that graphically presents a large volume of data in such a way that the central tendency (average/mean, etc.) and distribution are clearly displayed. The arrangement of data into classes or interval groups www.oly-wa.us/sqn/Glossary.htm A tabular summary of data showing the number (or frequency) of items in each of several non-overlapping classes. www.swcollege.com/quant/asw/embs_2e/glossary.html A means of summarizing large amounts of data to permit their interpretation in a simple graphic. www.eskimo.com/~hwa/glossary/glo_f.html a table showing the number of items that fall within each of a number of equal ranges or class intervals. www.ivey.uwo.ca/intl_students/dictionary/MS_dic.htm A tabulation of the number of individuals in each category on the scale of measurement. www.public.coe.edu/departments/Psychology/PsychStat/glossaries/glossary%20chapter.htm In media it shows the number of people reached 1, 2, .....n times. www.rmsmedia.co.za/glossary.html The target audience reached by a message is divided into groups depending on how many times they were reached. www.horizonmedia.com/glossary/f.htm A method of displaying test scores. www.wrightslaw.com/links/glossary.assessment.htm A grouping of data into categories showing the number of observations in each mutually exclusive category. highered.mcgraw-hill.com/sites/0072471042/student_view0/chapter2/glossary.html Displays how the cumulative audience for a schedule has built in percentage terms - once, twice, three times etc. Example (Men 25-39): 1 2 3 4 5 6 7 8 9 10+ www.mediafederation.org.au/glossary.html a distribution of observed frequencies of occurrence of the values of a variable www.cogsci.princeton.edu/cgi-bin/webwn
