line graph

a graphic technique used to illustrate the relationship between continuous measurements

mean

a measure of central tendency that is determined by calculating the arithmetic average of observations in a frequency distribution

measures of central tendency

the typical or average numbers that are descriptive of the entire collection of data for specific population

measures of variability

examination of the spread of different values around the measures of central tendency these include the range variance and standard deviation

median

a measure of central tendency that serves the midpoint of a frequency distribution when the observation have been arranged from lowest to highest

mixed methodology

research study approach that includes both quantitative and and qualitative data

mode

a measure of central tendency that consists of the most frequent observation in a frequency distribution

nominal variables

variables in which a number is assigned to a specific category such as 1=male 2= female

normal distribution

a theoretical family of continuous frequency distributions characterized by a symmetric bell

ordinal variables

ranked variables in which a number is assigned to rank category in an ordered series but does not indicate the magnitude of difference between data points

pareto chart

a bar graph that includes bars arranged in order of descending size to show decisions on the prioritization of issues problems and solutions

pie chart

a graphic technique in which the proportions of a category are displayed as portions of a circle used to show individual to part of a whole

presentation software

software used to build slides when presenting a a specific topic idea research data or any type of information

Propotion

The relation of one part to another or to the whole with respect to magnitude quantity or degree

Prospective study

A study designed to observe outcomes or events that occur after identification of a group of subjects to be studied

Qualitive research

Research design that collects types of data that include a participants perceptions attitudes feelings attitudes about a certain subject methods used to collect qualities data can include observations focus groups case studies informal conversational interviews. And in depth interviews

Qualitative variables

Categorical variables all are discrete and include both nominal and ordinal variables

Quantitative. study

Data collected for research studies. That are collated numerically with descriptive infernal or predictive statistics

Quasi experimental. Study

Similar to the experimental study except that randomization of participants is not included in a quasi experimental study the independent. Variable may not be manipulated by the researcher and there may be no control or comparison group these studies can be performed. Over. Time

Randomization

The assignment. Of subjects to experimental or control groups based on chance

Range

A measure of variability. Between. The smallest and largest observations in a frequency distribution

Ratio variables

The most common quantative variables used in healthcare these variables include numbers that can be compared meaningfully. With one another zero is truly zero on the ratio scale

Research methodologies

Research studies. That can range from exploratory. To descriptive. Studies. That strive to generate new hypotheses. Based on data. Collected for expire mental studies. That provide intervention or treatments that can reduce the spread of an existing. Disease

Retrospective. Study

A type of research conducted by reviewing records from the past or by obtaining information about past events through surveys or interviews

Scatter charts

A graph visually. Displays the linear relationships. Among facts

Standard deviation

A measure of variability. That describes the deviation fron the mean of a frequency distribution in the original units of measurements. The square root of variance

Stem and leaf plots

A visual display that organizes data to show. Its shape and distribution using two columns with tue stem in the left hand and the column and leaves associated with that stem in the rigth hand colum leaf is the ones digits of the bumber and the other digits from the stem

Statistical packages

Software that can be used to facilitate the data collection and analysis process these packages simplify. The statistical. Analysis. Of the data often used in addition to spreadsheet software

Table

…an organized arrangement of data usually in columns. And rows

Variability

Range variance and standard deviation

Variance

…a disagreement between two parts the squares of standard deviation a measure of variability. That give the average squared deviation s from the mea.
