2. Computer Assisted Data Analysis
 Advances in technology have provided new approaches for
data collection methods and analysis for researchers.
 Data collection is no longer limited to paper-and-pencil
format, and numerous methods are now available through
Internet and electronic resources.
 With these techniques, researchers are not burdened with
entering data manually and data analysis is facilitated by
software programs.

3. Data Analysis Software
 Data analysis Software tool that has the statistical and analytical
capability of inspecting, cleaning, transforming and modeling data with
an aim of driving important information for decision making purposes.
 Data analysis can be classified as Descriptive statistics, exploratory data
analysis (EDA) and confirmatory data analysis (CDA).
 We can Analyze our data by different softwares, Such as:
1. SPSS
2. MS-Excel
3. Statistics Calculators (on Smart phones)

4. Example:
 Find the Descriptive Statistics of
given Value with the help of
Computer Assisted Data Analysis:
6, 8, 11, 5, 2, 9, 7, 8.
 Here, I used an Application
software (statistics calculator) to
analyze the given data. The
software asked me sample size and
values, which I entered as
provided me.
 Then it showed the descriptive
statistics.

5.  Here, in result this software
provided me every thing within
seconds.
 It gave me Mean, Mode , Median,
Range, Variance, standard
Deviation and many More.
 Hence, It saves my time and
present accurate calculation.

6.  Here I used another software to
analyze particular data, this
software gave me options to
Calculate the descriptive statistics
(Mean, Mode, Median, Range,
Variance and Standard deviation )
one by one or by selecting ALL.
 I opted ALL and it present me the
result, which is displayed on next
slide.

8.  This software also sketched
Histogram and Cumulative
frequency graph without any
restriction.
 As shown in given screen shots.
 Hence computer technology and
such types of softwares have made
statistics more easier than ever.
