Data analysis involves editing, coding, sorting, and entering data to discover useful information. The process includes gathering data from various sources, reviewing it, and analyzing it to form conclusions. Specifically, editing ensures quality by reviewing collected data, coding categorizes data for computer analysis, sorting arranges data in a meaningful order for comprehension, and data entry inputs collected information into a computer. Finally, a master chart compiles all essential data in one format.

2. Data analysis
 Data analysis is a process of inspecting, cleansing, transforming, and
modeling data with the goal of discovering useful information, informing
conclusions, and supporting decision-making. ...
 The process of evaluating data using analytical and logical reasoning to
examine each component of the data provided. ... Data from various sources is
gathered, reviewed, and then analyzed to form some sort of finding or conclusion.

4. Editing
 Data editing is defined as the process involving the review and adjustment of
collected survey data. The purpose is to control the quality of the collected data.
Data editing can be performed manually, with the assistance of a computer or a
combination of both.
 Data collected through questionnaire and schedules may have answers which
may not be ticked at proper places, or some questions may be left unanswered.
Sometimes information may be given in a form which needs reconstruction in a
category designed for analysis

5. Coding
 Coding is an analytical process in which data, in both quantitative form (such as questionnaires
results) or qualitative form (such as interview transcripts) are categorized to facilitate analysis.
One purpose of coding is to transform the data into a form suitable for computer-aided analysis.
 This categorization of information is an important step, for example, in preparing data
for computer processing with statistical software.

6. Sorting
 Data sorting is any process that involves arranging the data into some
meaningful order to make it easier to understand, analyze or visualize. When
working with research data, sorting is a common method used for
visualizing data in a form that makes it easier to comprehend the story the data is
telling.
 Sorting can be done with raw data (across all records) or at an aggregated level (in
a table, chart, or some other aggregated or summarized output).

7. Data Entry
 Once data collection has been completed and checked, the process of data entry
and cleaning starts. During data entry the verbal or numeric data collected using
questionnaires, abstraction forms, or observations are entered into a computer

8. Master Chart
 Once data entry is completed the chart prepared using diagrams or tables.
 Master chart contains all essential data in one form
