HOW I USED THE KNOWLEDGE GOTTEN FROM DATA ANALYSIS with vertex.

On my last class on DATA ANALYSIS with vertex.
We did a descriptive analysis involving a large data set and the knowledge gotten inspired me to carry out a survey via questionnaire on a particular business idea I and my friend are working on. I used the way I was taught to perform my analysis using SPSS the acronym of STATISTICAL PACKAGE FOR SOCIAL SCIENCES.
SPSS has more functionalities and ease my analysis.

SPSS has two view which are the VARIABLE VIEW and the DATA VIEW.

The VARIABLE VIEW is where I will structure how my data will look like. There are Eleven (11) columns there and each has it’s own function.

For the first column NAME, I input the name of my variable there but without symbols and space, because it doesn’t accept any of that, but the only column that allows that is the LABEL column, there I can put my variable name any how.

Then for the second column which is TYPE column, here I indicate whether my value is numerical or it’s in string format or it’s in any other format. etc

The WIDTH column works with the string type and I indicate the number of character my string carries in the WIDTH column.

So also the DECIMAL column works with the numerical type of data. When my data is the measurement type of data (i.e 10.45, 34.56, etc) then the DECIMAL column will contain '2’.

For the VALUE column, each cell has a box at it’s edge, clicking it pops out a dialog box. So to input my value here I click the box and indicate the way my variable is coded (i.e 1 for MALE and 2 for FEMALE).

Then if I get any missing value in any of the variable and I want my analysis to run without the missing data, then I will indicate it in the MISSING column.

Then align my data to the center
I fix NORMINAL because the values of my numeric data differs and ORDINAL when my values are not scalable (i.e data of MALE and FEMALE) then SCALE for when my data is continuous all on MEASURE column.

Then since I’m inputting values, I leave my ROLE column as input.

Then to my DATA VIEW, I code the questionnaire and input all of the data I got in the coded form and then I analyze by clicking ANALYZE on the menu bar then scroll to Descriptive and click Frequency, then checked the box named Display frequency and I sent every of my variable to a variable box through an arrow.

To complete my analysis, I click on statistics and highlight MEAN MEDIAN MODE.

Then I also selected a BAR CHART in the chart button.
After clicking ok, I got an analysis on MEAN MEDIAN MODE of each variable and I saw a clear difference of the responses on the bar chart.

Based on the business idea I and my friend are working on, this analysis gave me a clear overview of what people want and how to give it to them.
It also showed a particular age needs and what a particular location like doing the most.
