WEEK 1 Flashcards
is the manipulation of the data gathered using descriptive and inferential statistics.
Analysis
is used in getting the value for the median, quartiles, deciles, and percentiles.
Cumulative frequency
point to statistical facts, principles, opinions and various items of different sources.
Data
is the process and methods of gathering information by interview, questionnaire, experiments, observation and documentary analysis
Data collection
takes the form of tables and graphs.
Data presentation
includes frequency distribution, measures of central tendency, measures of central location, measures of dispersion or variation, graphs, skewness and kurtosis. Likewise, it refers to some techniques which are concerned with the presentation and collection of data or information.
Descriptive statistics
is the tabulation of data of measures. grouped with class intervals.
Frequency distribution
points to the construction of bar graphs, frequency polygons, pie charts, and pictographs, among others.
Graphical presentation
are properly organized and classified data such as the use of frequency distribution.
Grouped data
is the technique by which decision and conclusion are to be made from the population observed using only the representative samples. This statistics includes both parametric and nonparametric tests which are more concerned with generalizing information or making inference about the population through representative samples.
Inferential statistics
makes clear results of the analysis using statistical methods to see whether significant differences or relationships exist between variables.
Interpretation
is a characteristic of a population.
Parameter
is the totality of all the actual observable characteristics of a set of objects or individuals.
Population
involves the selection of samples such that each sample of a given size has precisely the probability of being selected. It includes the simple random, stratified, cluster and multistage sampling techniques. sampling
Random Sampling
refers to the element of objects or individuals selected from the population.
Sample
is the extensive set of question and instruction used in personal interview.
Schedule
is the art and science of collecting, presenting. analyzing and interpreting data. These data may be in sports, business, politics, education and practically all fields of human endeavor dealing with statistics.
Statistics
are measures like feet, pounds, kilos, minutes, and meters. These kinds of data can be made into measurement of varying degrees of precision, for example, 1 yard equals 3 feet, 1 foot equals 12 inches.
TYPES OF DATA
Continuous data
are measurement expressed in whole units. Counting of people, number of objects, number of cars passing by, number of houses, number of students, workers, and so on.
TYPES OF DATA
Discontinuous or discrete data
is the method of collecting and presenting data. It includes the computation of measures of central tendency, measures of central location, likewise the measures of dispersion or variability. It also includes the construction of tables and graphs.
MAJOR F(X)’S OF STATISTICAL INVESTIGATION
Descriptive Statistics
is concerned with higher degree of critical judgment and advanced mathematical modes such as using the different statistical tools both the parametric and nonparametric tests. This is concerned with the analysis and interpretation of data in order to draw conclusion and generalization from organized data. This also includes the testing of the significant relationship between the dependent and the independent variables as well as the significant differences between and among independent samples.
