Data Organization

Organizing raw data into a simplified and meaningful format to gain insights from the results.

Raw Data

Data that is not organized, typically in its original form, like responses from a survey.

Data Classification

Arranging data into groups based on shared characteristics to make analysis easier. Examples include classifying data by religion, gender, age, or location.

Tabulation

Presenting classified data in a structured format using rows and columns. It's the process of creating tables.

Study Notes

Data Presentation - Tabulation

  • Data presentation involves organizing and simplifying data to gain a general overview of results.
  • Raw data is unorganized data, often from surveys or similar sources.
  • Ungrouped data is data in its original, unorganized form.
  • Data organization methods include classification (qualitative, quantitative, etc.), tabulation (simple, frequency, stem-and-leaf), and graphs (bar, pie, charts, histograms, etc.).

Data Classification

  • Data classification is arranging data into homogeneous groups or classes based on common characteristics.

Bases of Data

  • Qualitative: e.g., religion, gender, color
  • Quantitative: e.g., height, age, weight
  • Geographical: e.g., location, states, cities
  • Chronological/Temporal: e.g., time of occurrence (years, months, weeks), time series data

Types of Data

  • One-way class: single characteristic (e.g., world population based on religion)
  • Two-way class: two characteristics (e.g., world population based on religion and gender)
  • Multi-way class: multiple characteristics (e.g., world population based on religion, gender, literacy)

Tabulation of Data

  • Tabulation is the process of presenting classified data in a tabular format.
  • A table is a structured arrangement of statistical data into rows and columns.
  • Rows are horizontal arrangements of data.
  • Columns are vertical arrangements of data.

Types of Tables

  • Simple/One-way table
  • Double/Two-way table
  • Complex/Multi-way table

General Rules of Tabulation

  • Tables should be simple and attractive.
  • Complex tables should be divided into simpler tables.
  • Column and row headings should be clear and proper.
  • Suitable approximations and rounded figures should be noted in the prefatory or footnote.
  • Units of measurement and data nature should be well-defined.

Organizing Data via Frequency Tables

  • Frequency distribution is organizing data into classes or groups with the corresponding count in each category.
  • Class frequency is the count of observations in a particular class or group.
  • Grouped data is data presented using a frequency distribution.

What is Frequency Distribution?

  • Frequency distribution visually displays the frequency of outcomes in a repeatable event.

Main Parts of a Frequency Distribution

  • Title (e.g., school/university data)
  • Box/Column captions
  • Stub/Row captions
  • Data body

Example of frequency distribution (Weights in pounds of 40 students):

  • Table including classes, tally marks, and frequency of observations will be needed to answer this part.

Relative Frequency Distribution

  • Relative frequency illustrates the proportion of observations in each class to the total number of observations.
  • Calculate relative frequency by dividing the frequency of a class by the total number of observations.

Frequency Distribution of Qualitative Data (Political Party Affiliations):

  • Data tabulation with political party affiliations (e.g., PML-N, PPP, PTI, PML-Q), frequencies, and tally marks
  • Interpretation of data (e.g., percentage breakdown of affiliation).

Cumulative Frequency Distribution

  • Cumulative frequency distribution displays the total frequencies up to a certain point.
  • It showcases the total number of observations that fall below or above particular values.

Stem and Leaf Plot

  • A quick and clear method for sorting and displaying data simultaneously in a visual format. -Data is separated into stems and leaves (leading and trailing digits) with corresponding values in rows.
    • Example showing how to construct a stem and leaf plot will be provided
