Data Module #1: What is Research Data?

One goal of statistics is to present data in a meaningful way. This is far too many to print out in a journal article or sidebar of a magazine story. That's where graphs can be invaluable, allowing statisticians to provide a visual interpretation of complex numerical stories.

Seven types of graphs are commonly used in statistics. Good graphs convey information quickly and easily to the user. Graphs highlight the salient features of the data. They can show relationships that are not obvious from studying a list of numbers. They can also provide a convenient way to compare different sets of data.

Different situations call for different types of graphs, and it helps to have a good knowledge of what types are available. The type of data often determines what graph is appropriate to use. Qualitative data , quantitative data , and paired data each use different types of graphs. Data is displayed either horizontally or vertically and allows viewers to compare items, such as amounts, characteristics, times, and frequency.

The bars are arranged in order of frequency, so more important categories are emphasized. By looking at all the bars, it is easy to tell at a glance which categories in a set of data dominate the others.

The results were striking: They showed dramatically the disparity between rich and poor in each era over the course of centuries. It gets its name from the way it looks, just like a circular pie that has been cut into several slices.

Each slice of pie represents a different category, and each trait corresponds to a different slice of the pie; some slices usually noticeably larger than others.

By looking at all of the pie pieces, you can compare how much of the data fits in each category, or slice. A histogram in another kind of graph that uses bars in its display.

This type of graph is used with quantitative data. Ranges of values, called classes, are listed at the bottom, and the classes with greater frequencies have taller bars.

A histogram often looks similar to a bar graph, but they are different because of the level of measurement of the data. Bar graphs measure the frequency of categorical data.

A categorical variable is one that has two or more categories, such as gender or hair color. Histograms, by contrast, are used for data that involve ordinal variables, or things that are not easily quantified, like feelings or opinions. A stem and leaf plot breaks each value of a quantitative data set into two pieces: a stem, typically for the highest place value, and a leaf for the other place values. It provides a way to list all data values in a compact form.

For example, if you are using this graph to review student test scores of 84, 65, 78, 75, 89, 90, 88, 83, 72, 91, and 90, the stems would be 6, 7, 8, and 9, corresponding to the tens place of the data.

This would show you that four students scored in the 90th percentile , three students in the 80th percentile, two in the 70th, and only one in the 60th. You'd even be able to see how well students in each percentile performed, making this a good graph to understand how well students comprehend the material.

A dot plot is a hybrid between a histogram and a stem and leaf plot. Each quantitative data value becomes a dot or point that is placed above the appropriate class values. Where histograms use rectangles—or bars—these graphs use dots, which are then joined together with a simple line, says statisticshowto.

A scatterplot displays data that is paired by using a horizontal axis the x-axis , and a vertical axis the y-axis. The statistical tools of correlation and regression are then used to show trends on the scatterplot. A scatterplot usually looks like a line or curve moving up or down from left to right along the graph with points "scattered" along the line.

The scatterplot helps you uncover more information about any data set, including:. A time-series graph displays data at different points in time, so it is another kind of graph to be used for certain kinds of paired data. As the name implies, this type of graph measures trends over time, but the timeframe can be minutes, hours, days, months, years, decades, or centuries.

For example, you might use this type of graph to plot the population of the United States over the course of a century. The y-axis would list the growing population, while the x-axis would list the years, such as , , Share Flipboard Email. Courtney Taylor. Professor of Mathematics. Courtney K. Taylor, Ph.

7 Graphs Commonly Used in Statistics

In statistics , a misleading graph , also known as a distorted graph , is a graph that misrepresents data , constituting a misuse of statistics and with the result that an incorrect conclusion may be derived from it. Graphs may be misleading through being excessively complex or poorly constructed. Even when constructed to accurately display the characteristics of their data, graphs can be subject to different interpretation, or unintended kind of data can seemingly and ultimately erroneously be derived. Misleading graphs may be created intentionally to hinder the proper interpretation of data or accidentally due to unfamiliarity with graphing software , misinterpretation of data, or because data cannot be accurately conveyed. Misleading graphs are often used in false advertising. One of the first authors to write about misleading graphs was Darrell Huff , publisher of the book How to Lie with Statistics.

The proper understanding and use of statistical tools are essential to the scientific enterprise. This is true both at the level of designing one's own experiments as well as for critically evaluating studies carried out by others. Unfortunately, many researchers who are otherwise rigorous and thoughtful in their scientific approach lack sufficient knowledge of this field. This methods chapter is written with such individuals in mind. Although the majority of examples are drawn from the field of Caenorhabditis elegans biology, the concepts and practical applications are also relevant to those who work in the disciplines of molecular genetics and cell and developmental biology.

Thus, graph theory has more practical application particulars in solving electric network. No matter if, we adopt new analytical methods or technical means, we must have a distinct recognition of electric power system itself and its complexity, and increase analysis continuously, operation and control level. It reflects the current state of the subject and emphasizes connections with other branches of pure mathematics. Computer and software engineers apply graph theory as algorithms and computations.

7 Graphs Commonly Used in Statistics

В центре находился красный кружок с надписью БАЗА, вокруг которого располагались пять концентрических окружностей разной толщины и разного цвета. Внешняя окружность была затуманена и казалась почти прозрачной. - У нас имеется пять уровней защиты, - объяснял Джабба.  - Главный бастион, два набора пакетных фильтров для Протокола передачи файлов, Х-одиннадцать, туннельный блок и, наконец, окно авторизации справа от проекта Трюфель. Внешний щит, исчезающий на наших глазах, - открытый главный компьютер. Этот щит практически взломан.

Фонтейн пришел к выводу, что Стратмор в полном порядке, что он трудится на сто десять процентов, все так же хитер, умен и в высшей степени лоялен, впрочем - как. Лучшее, что мог сделать директор, - не мешать ему работать и наблюдать за тем, как коммандер творит свое чудо. Стратмор разработал план… и план этот Фонтейн не имел ни малейшего намерения срывать. ГЛАВА 75 Пальцы Стратмора время от времени касались беретты, лежавшей у него на коленях. При мысли о том, что Хейл позволил себе прикоснуться к Сьюзан, кровь закипела в его жилах, но он помнил, что должен сохранять ясную голову, Стратмор с горечью признал, что сам отчасти виноват в случившемся: ведь именно он направил Сьюзан в Третий узел.

Это на нижнем этаже. Возле фреоновых помп. Сьюзан повернулась и направилась к двери, но на полпути оглянулась.

Неужели попал зараженный файл? - подумал.  - Неужели фильтры безопасности что-то пропустили. В целях безопасности каждый файл, загруженный в ТРАНСТЕКСТ, должен был пройти через устройство, именуемое Сквозь строй, - серию мощных межсетевых шлюзов, пакетных фильтров и антивирусных программ, которые проверяли вводимые файлы на предмет компьютерных вирусов и потенциально опасных подпрограмм. Файлы, содержащие программы, незнакомые устройству, немедленно отвергались.

Повисла пауза. Стратмор поднял глаза вверх, собираясь с мыслями. - Сьюзан, - наконец произнес он еле слышно.  - У меня нет семьи.  - Он посмотрел на .

В международном аэропорту Далласа девушку встретил шофер АНБ, доставивший ее в Форт-Мид. В тот год аналогичное приглашение получили еще сорок кандидатов. Двадцативосьмилетняя Сьюзан оказалась среди них младшей и к тому же единственной женщиной. Визит вылился в сплошной пиар и бесчисленные интеллектуальные тесты при минимуме информации по существу дела. Через неделю Сьюзан и еще шестерых пригласили .

 - Мы вместе спустимся.  - Он поднял беретту.  - Ты найдешь терминал Хейла, а я тебя прикрою. Сьюзан была отвратительна даже мысль об .

Мидж изумленно всплеснула руками. - И там и там уран, но разный. - В обеих бомбах уран? - Джабба оживился и прильнул к экрану.

Умница, да к тому же единственная женщина, не упускавшая случая с ним пококетничать.  - Как твои дела. - Не жалуюсь.

 Черт возьми! - не сдержался Фонтейн, теряя самообладание.  - Он должен там. Ищите.

 - Стратмор говорит, что у нас неверные данные. Бринкерхофф кивнул и положил трубку. - Стратмор отрицает, что ТРАНСТЕКСТ бьется над каким-то файлом восемнадцать часов. - Он был крайне со мной любезен, - просияв, сказал Бринкерхофф, довольный тем, что ему удалось остаться в живых после телефонного разговора.
