Is first stage involve the collection of data geographer use both primary and secondary data
Collection
Organization
A large mass of figure collected from survey often needs organization, this is the second stage
Involves the arrangement of raw data in well organized manner
Presentation

Analysis
The purpose of analysis data is to get only some information for the making decisions
Interpretation
This is the stage involve the drawing of conclusion
Question1
Nominal data is the type of data that is used to label the variable without providing any
Quantitative .From the data obtained nominal data is male and female

Ordinal data are often used for measure of satisfaction, happiness and soon
Ordinal data from obtained information is strong agree three members and neither agree nor
Disagree three members
The interval is21_25or ratio 21:25
Question2
The discrete data is the data that can't be broken down in to smallest unit and additional
Meaning. It is typically thing counted in whole number From data obtained the discrete data
number of respondent which is 6
Question 3
Mode is value which appeared many times than other. From the information obtained
Mode of the age is 21and 22
Mode of marital status is 6
Percentile is the data set that splits the data in two pieces,
Required to calculate the percentiles of variable
Where21, 21, 22 ,22, 23 ,25.
21+21+22+22+23+25=134
21/134×100℅=15.67℅
21/134×100℅=15.67℅
22/134×100℅=16.41℅
22/134×100%=16.41℅
