It is based on statistical theory which is a branch of applied mathematics. Within statistical theory, randomness and uncertainty are modelled by probability theory Wikipedia Encyclopedia. What is statistics? There are basic steps depending on the subject matter and researcher.

There are many advantages to using secondary data, and Fraser Health has a large number of data sets available for analysis. A dependent variable may also be the variable you are trying to predict. Calcium is measured in milligrams, and foot size is measured in centimetres. Researcher Purple hypothesizes that calcium affects foot size. Researcher Orange hypothesizes that orange juice affects male pattern baldness. Researcher Blue hypothesizes that pet type will affect level of happiness.

Descriptive Statistics DefinedWhat is a mean? Mean The Mean"A statistician is someone who can have his head in an oven and his feet in ice, and say that on the average he feels great. MedianA median is the middle of a distribution. For example, the median of 5, 8, and 11 is 8. ModeWhat is a mode? To calculate variance, the mean of a group of scores is subtracted from each score to give a group of 'deviations'.

HypothesesNull hypothesis: A hypothesis put forward to argue that a relationship or pattern does not exist. Cholesterol study example: In a Randomized Control Trial, the control group and the treatment group have equal levels of cholesterol at the end of a study. Null hypothesis: Groups A and B are equal. Alternative Hypothesis: Groups A and B have different levels of cholesterol.

The null hypothesis will be true if the findings are insignificant. The null hypothesis will be false if the findings are significant. Denoted by H1: AlphaAlpha level, or significance level, is the value that is determined by the researcher in order to reject or retain the null hypothesis.

It is a pre-determined value, not calculated. What does this mean? What if your study finds there is an effect? So, you can't take the rate of disease in both populations in order to calculate RR.

Involves discovering the equation for a line that is the best fit for the given data. That linear equation is then used to predict values for the data. Appreciate statistics for the important role they play, but do not let statistics prevent you from posing new and exciting research questions. Example: if you have a 1 in 3 chance of winning a draw, your odds are Smokers are 2.

### Quantitative and Statistical Research Methods: From Hypothesis to Results

Rhetorical research methods have been being developed since the Classical Period. As the transition was made to seeing communication from a social scientific perspective, scholars began studying communication using the methods established from the physical sciences. Thus, quantitative methods represent the steps of using the Scientific Method of research. The term quantitative refers to research in which we can quantify, or count, communication phenomena. Quantitative methodologies draw heavily from research methods in the physical sciences explore human communication phenomena through the collection and analysis of numerical data.

Quantitative methods emphasize objective measurements and the statistical, mathematical, or numerical analysis of data collected through polls, questionnaires, and surveys, or by manipulating pre-existing statistical data using computational techniques. Quantitative research focuses on gathering numerical data and generalizing it across groups of people or to explain a particular phenomenon. Babbie, Earl R. The Practice of Social Research. Your goal in conducting quantitative research study is to determine the relationship between one thing [an independent variable] and another [a dependent or outcome variable] within a population. Quantitative research designs are either descriptive [subjects usually measured once] or experimental [subjects measured before and after a treatment]. A descriptive study establishes only associations between variables; an experimental study establishes causality.

Hola. Тишина. Наверное, Меган, подумал. У нее оставалось целых пять часов до рейса, и она сказала, что попытается отмыть руку. - Меган? - позвал он и постучал .

Стремительно исчезал уровень авторизации файлов - последняя линия обороны. А у входа толпились бандиты. - Внимание! - скомандовал Фонтейн. Соши смотрела на монитор и читала вслух: - В бомбе, сброшенной на Нагасаки, использовался не плутоний, а искусственно произведенный, обогащенный нейтронами изотоп урана с атомным весом 238.

- Потом в его голосе зазвучали зловещие нотки.

Бедняга. Сердечный приступ. Беккер безучастно кивнул: - Так мне сказали. Лейтенант вздохнул и сочувственно помотал головой.

Открыв ее, она увидела несколько дополнительных папок; создавалось впечатление, что у Хейла было множество почтовых адресов. Один из них, к ее удивлению, был адресом анонимного провайдера. Сьюзан открыла одно из старых входящих сообщений, и у нее тотчас же перехватило дыхание. ТО: NDAKOTAARA.

Она начала двигаться в направлении люка. В воздухе ощущался едва уловимый запах озона. Остановившись у края люка, Сьюзан посмотрела. Фреоновые вентиляторы с урчанием наполняли подсобку красным туманом. Прислушавшись к пронзительному звуку генераторов, Сьюзан поняла, что включилось аварийное питание.

Текст, набранный крупным шрифтом, точно на афише, зловеще взывал прямо над его головой: ТЕПЕРЬ ВАС МОЖЕТ СПАСТИ ТОЛЬКО ПРАВДА ВВЕДИТЕ КЛЮЧ_____ Словно в кошмарном сне Сьюзан шла вслед за Фонтейном к подиуму. Весь мир для нее превратился в одно смутное, медленно перемещающееся пятно. Увидев их, Джабба сразу превратился в разъяренного быка: - Я не зря создал систему фильтров. - Сквозь строй приказал долго жить, - безучастно произнес Фонтейн. - Это уже не новость, директор.

Она знала, что цепная мутация представляет собой последовательность программирования, которая сложнейшим образом искажает данные. Это обычное явление для компьютерных вирусов, особенно таких, которые поражают крупные блоки информации. Из почты Танкадо Сьюзан знала также, что цепные мутации, обнаруженные Чатрукьяном, безвредны: они являются элементом Цифровой крепости.
