What does statistical analysis mean? Statistical analysis is
the collection and interpretation of data in order to uncover patterns and trends
. It is a component of data analytics. Statistical analysis can be used in situations like gathering research interpretations, statistical modeling or designing surveys and studies.
Why do we need statistical analysis?
Statistical knowledge
helps you use the proper methods to collect the data, employ the correct analyses, and effectively present the results
. Statistics is a crucial process behind how we make discoveries in science, make decisions based on data, and make predictions.
What are the 5 basic methods of statistical analysis?
It all comes down to using the right methods for statistical analysis, which is how we process and collect samples of data to uncover patterns and trends. For this analysis, there are five to choose from:
mean, standard deviation, regression, hypothesis testing, and sample size determination
.
What type of research is statistical analysis?
Statistical data analysis is a procedure of performing various statistical operations. It is a kind of
quantitative research
, which seeks to quantify the data, and typically, applies some form of statistical analysis. Quantitative data basically involves descriptive data, such as survey data and observational data.
What is a statistical analysis plan?
The Statistical Analysis Plan (SAP) Sample Template for Clinical Trials is
a technical document that describes in detail the planned statistical analysis of a clinical trial as outlined in the protocol
. Although the SAP is a standalone document, it should be reviewed in conjunction with the protocol.
Although statistical analysis and data analysis bear several similarities, the primary difference between a statistical analyst and a data analyst is
their unique approach to using data analytics tools and processes
.
A simple example of Data analysis is
whenever we take any decision in our day-to-day life is by thinking about what happened last time or what will happen by choosing that particular decision
. This is nothing but analyzing our past or future and making decisions based on it.
A good outline is:
1) overview of the problem, 2) your data and modeling approach, 3) the results of your data analysis (plots, numbers, etc), and 4) your substantive conclusions
. Describe the problem. What substantive question are you trying to address? This needn’t be long, but it should be clear.
A necessary companion to well-designed clinical trial is its appropriate statistical analysis. Assuming that a clinical trial will produce data that could reveal differences in effects between two or more interventions, statistical analyses are
used to determine whether such differences are real or are due to chance
.
Definition of statistics
1 :
a branch of mathematics dealing with the collection, analysis, interpretation, and presentation of masses of numerical data
. 2 : a collection of quantitative data.
Types of Data in Statistics (4 Types –
Nominal, Ordinal, Discrete, Continuous
)
- Measure of frequency.
- Measure of dispersion.
- Measure of central tendency.
- Measure of position.

Descriptive and inferential
are the two general types of statistical analyses in quantitative research.
