SPSS Training in Ikeja Lagos Nigeria

SPSS for Advanced Analytics

SPSS was developed to do most major types of data analysis using SPSS. The software was originally created by three Stanford graduate students in the late 1960s. The acronym “SPSS” initially stood for “Statistical Package for the Social Sciences.” As SPSS expanded their package to address the hard sciences and business markets, the name changed to “Statistical Product and Service Solutions.” In 2009 IBM purchased SPSS and the name morphed to “IBM SPSS Statistics.” SPSS is now such a standard in the industry that IBM has retained the name due to its recognizability. No one particularly cares what the letters “SPSS” stand for any longer. IBM SPSS Statistics is simply one of the world’s largest and most successful statistical software companies.


The SPSS Environment

SPSS mainly uses two windows: the data editor (this is where you input your data and carry out statistical functions) and the viewer (this is where the results of any analysis appear). There are several additional windows that can be activated such as the SPSS Syntax Editor, which allows you to enter SPSS commands manually (rather than using the window-based menus). For many people, the syntax window is redundant because you can carry out most analyses by clicking merrily with your mouse.


Once SPSS has been activated, a start-up window will appear, which allows you to select various options. If you already have a data file on disk that you would like to open then select Open an existing data source.


Functions of the various features in SPSS

File: This menu allows you to do general things such as saving data, graphs or output. Likewise, you can open previously saved files and print graphs data or output. In essence, it contains all of the options that are customarily found in File menus.


Transform: For example, you can use recode to change the values of certain variables (e.g. if you wanted to adopt a slightly different coding scheme for some reason). The compute function is also useful for transforming data (e.g. you can create a new variable that is the average of two existing variables). This function allows you to carry out any number of calculations on your variables.


Analyze: The fun begins here, because the statistical procedures lurk in this menu. This feature houses majority of the statistical tests in SPSS.


Defining Your Hypothesis in SPSS

Scientific statements, as we have seen, can be split into testable hypotheses. The hypothesis or prediction that comes from your theory is usually saying that an effect will be present. This hypothesis is called the alternative hypothesis and is denoted by H1. (It is sometimes also called the experimental hypothesis but because this term relates to a specific type of methodology it’s probably best to use ‘alternative hypothesis’.) There is another type of hypothesis, though, and this is called the null hypothesis and is denoted by H0. This hypothesis is the opposite of the alternative hypothesis and so would usually state that an effect is absent.


Taking our Productivity example that we might generate the following hypotheses:


Alternative hypothesis: Men will score higher on productivity questionnaires than women.

Null hypothesis: Men will not score higher than women with respect to productivity.

Python is an object-oriented programming language used for high-level and general-purpose programming, not the literal reptile. As an Object-oriented programming language, it refers to data in the form of fields and code as procedures that allow a modification to data fields. Python is an interpreter that converts intermediate language to machine language.


Around 1991 saw the initial publication of Guido Van Rossum’s Python programming language. Its source code may be accessed by anyone under the terms of the GNU General Public License, which is a license issued by the Python Software Foundation. Over 48% of developers know how to use it, making it a simple language to pick up. Python is used by many prominent companies, including Intel, IBM, NASA, Pixar, Netflix, Facebook, JP Morgan Chase, Spotify, and many others. One of the four main languages utilized within the corporation, Python, is used to create the majority of Google’s YouTube content, Instagram, Reddit and Pinterest. Python training at Lagos Data School offers the ability to work for globally recognized, rapidly expanding corporations. In other words, find employment as a Python programmer with your ideal employer, such as Deloitte, Microsoft, Google, and others.


Python is a great place to start for individuals who are new to programming and coding. Given how simple it is to learn, it’s a fantastic place to start when learning programming. Python can be used to code by anyone because it is an open-source language. Because of its more English-like structure, Python is fairly simple to read and comprehend. You can figure out what each line of code does thanks to its simple structure. The development of Python is compatible with other operating systems like macOS, Linux/Unix, Windows, and Android.


Tech innovation captivates people everywhere, therefore it’s wonderful that Nigeria produces excellent developers. Lagos, the most populous metropolis in Nigeria and the second most populated city in Africa, gives many people the opportunity to work in the tech industry. Lagos Data School is located in the capital, Ikeja, and equips both individuals and corporate entities to participate in the expanding technology industry. Technology brings about development and Lagos Data School at Ikeja is keen to train minds for a better Nigeria and global deliveries in which Python programming is not exempted.



Approaches of Python Programming

  • Object-oriented approach: Python as an object-oriented programming (OOP) is built around the idea of “objects,” which are units of information that can also include code. Fields represent the data, while procedures represent the code.


  • Procedural approach: As a procedural programming, it is built on the idea of the procedure call and evolved from imperative programming. Simple computing steps must be performed in a sequence as part of a procedure. Any specified method could possibly be called at any time while a python program is running.


  • Reflective approach: Python programming has the capacity to investigate, introspect, and modify its own structure and behavior.


  • Functional approach: Python programs are created by applying and combining functions. Instead of a series of imperative statements that update the state of the system, functions as trees of expressions map values to other values.


  • Structured approach: Python program development is quick, clear and reliable. Python can easily be referred to as a multi-paradigm language since it experiments with several approaches for more advanced expertise.



What can you do with Python programming?

As a general purpose programming language, python can be used for web development, Data visualization and analytics, programming of other languages, game development, Search Engine Optimisation (SEO), managing finance, Artificial Intelligence (AI) and Machine learning.

Advanced Microsoft Excel Training in Lagos Nigeria

Microsoft Excel is one of the most popular applications for data analysis. Equipped with built-in pivot tables, they are without a doubt the most sought-after analytic tool available. It is an all-in-one data management software that allows you to easily import, explore, clean, analyze, and visualize your data. In this Microsoft Excel Training in Ikeja Lagos Nigeria, we will discuss the various methods of data analysis in Excel.


One of the many uses of Excel is to facilitate data entry. Error-free data entry is essential to accurate data analysis. Excel provides several methods for entering your data. Data sets can be entered manually from the keyboard or retrieved from a text file, database, or online Web sources. You can also have Excel automatically enter patterns of data for you, saving you the trouble of creating these data values yourself. You’ll study all of these techniques in this Microsoft Excel training in Ikeja Lagos Nigeria, but first you’ll work on entering data from the keyboard.


Microsoft Excel performs statistical function, which is the bedrock for data analysis. Statistics provides a way to study how people and things respond to the world and, as such, it’s a fascinating, annoying, and sometimes contrary field to work in.




Descriptive statistics in particular seems to exercise a peculiar hold over some people. Some sports fans are able to rattle off the yearly betting averages, quarterback ratings, and/or assists per game achieved by their favorite players.


In the closely related area of inferential statistics, there are specialties such as test construction that depend heavily on the measurement of means, standard deviations, and correlations to create tests that not only measure what they are supposed to but do so with good accuracy.


Running A Statistical Test

A large number of questions in the areas of business, manufacturing, medicine, social science, gambling, and so on are based on situations in which there are just two typical outcomes: succeeds/fails, breaks/doesn’t break, cures/sickens, Republican/Democrat, wins/loses. In statistical analysis, these situations are termed binomial: “bi” referring to “two,” and “nomial” referring to “names.”

Several hundred years ago, due largely to a keen interest in the outcomes of bets, mathematicians started looking closely at the nature of those outcomes. We now know a lot more than we once did about how the numbers behave in the long run. And you can use that knowledge as a guide to an answer to the question posed earlier: How likely is it that there are at most 10 defectives in the production lot of 1,000 phones, when you found two in a sample of just 50?


Framing the Hypothesis

Start by supposing that you had a population of 100,000 phones that has 1,000 defectives—thus the same 1% defect rate as you hope for in your actual production lot of 1,000 phones.

This sort of supposition is often called a null hypothesis. It assumes that no difference exists between two values, such as a value obtained from a sample and a value assumed for a population; another type of null hypothesis assumes that no difference exists between two population values. The assumption of no difference is behind the term null

hypothesis. You often see that the researcher has framed another hypothesis that contradicts the null hypothesis, called the alternative hypothesis.
