math 1&2 (rev)

• a branch of mathematics which deals with collection, organization, analysis, and interpretation of data

  statistics
• looking on recorda file, collection of relevant information

  collection
• tabulating the important data


  presentation
• organizing all this information presented will provide basis for a persuasive presentation. arranging data


  organization
• examining more deeply the information presented will provide understanding of the characteristic the of the data


  analysis
• giving an opinion to the analysis made to the data will make more plausible and realible

  interpretation
• deals with the presentation and collection of data. first part of a statistical analysis. merely describing and uses graphs

  descriptive statistics
• involves drawing the right conclusion from the statistical analysis that has been performed using descriptive statistics. sample population (taking sample respondents / to represent)

  inferential statistics
• is a complete collection of all elements . entirity of group (entire)

  population
• is a sub-collection of elements drawn from a population . taking on population (not the entire)

  sample
• is a collection of facts such as numbers, words, measurements, observation or anything that suggest information

  data
• conceptualized and analyzed as distinct categories. without using/ no involves numbers

  qualitative data
• statistical steps in getting data

  collection

  organization

  presentation

  analysis

  interpretation
• two types of qualitative data


  nominal data

  ordinal data
• is a categories an element of a population (categorical)


  nominal data
• incorporates an ordered position, or ranking(arrangements). lowest to highest

  ordinal data
• any characteristics that we measure or count in numbers (involves numbers)

  quantitative data
• 2 types of quantitative data

  continuous data

  discrete data
• data which may take on any value in an given interval and it gives rise to measurements. assume infinites (cannot be counted)

  continuous data
• data take on any discrete value in a given interval values and it gives rise to counting. assume exact values (anything that can be counted)

  discrete data
• is the first step when doing statistics(collecting data). gathering statistical data
• gathering statistical data can be done by using any tool called as

  statistical instrument
• most often researcher ls use the blank or blank to gather the needed data for their study

  questionnaire or survey
• simply means collecting data needed of a certain study.

  data gathering
• is the process of gathering and measuring information on variable of interest

  data collection
• reffered as indirect method of gathering data because this makes use of written question to be answer by the respondents

  questionnaire
• requires the enactments of law to take effect because it needs the participation of a large, if not the entire population

  registration or census
• makes use of the different human senses in gathering information

  observation
• a direct method of gathering data because the data came directly from the source(personal).

  interview
• is usually conducted in laboratories where specimens are subjected to some aspects.of control to find out cause and effect relationship (used by scientists)

  experimentation
• involves gathering people from similar backgrounds or experiences together to discuss a specific topic of interest. it is a form of qualitative research 


  focus group discussion
• where questions are asked about their perceptions, attitudes, beliefs, opinions or ideas

  form of qualitative research
• is an arrangement of data that shows the frequency or occurrence of the different values in an experiment or study

  frequency distribution
• it is a systematic way of presenting data using a table

  frequency distribution table
