Data Cleaning Techniques: Learn Simple & Effective Ways To Clean Data

In this article, we will learn about the different data cleaning techniques and how to effectively clean data using them. Each technique is important and you also learn something new.

Top Data Cleaning Techniques to Learn
Let’s understand, in the following paragraphs, the different data cleaning techniques.

Remove Duplicates
The likelihood of having duplicate entries increases when data is collected from many sources or scraped. People making mistakes when keying in the information or filling out forms is one possible source of these duplications.

All duplicates will inevitably distort your data and make your analysis more difficult. When trying to visualize the data, they can also be distracting, so they should be removed as soon as possible.

Remove Irrelevant Data
If you’re trying to analyze something, irrelevant info will slow you down and make things more complicated. Before starting to clean the data, it is important to determine what is important and what is not. When doing an age demographic study, for instance, it is not necessary to incorporate clients’ email addresses.

There are various other elements that you would want to remove since they add nothing to your data. They include URLs, tracking codes, HTML tags, personally identifiable data, and excessive blank space between text.

Standardize Capitalization
It is important to maintain uniformity in the text across your data. It’s possible that many incorrect classifications would be made if capitalization were inconsistent. Since capitalization might alter the meaning, it could also be problematic when translating before processing.

Text cleaning is an additional step in preparing data for processing by a computer model; this step is much simplified if all of the text is written in lowercase.

Convert Data Types
If you’re cleaning up your data, converting numbers is probably the most common task. It’s common for numbers to be incorrectly interpreted as text, although computers require numeric data to be represented as such.

If they are shown in a readable form, your analytical algorithms will be unable to apply mathematical operations because strings are not considered numbers. Dates that are saved in a textual format follow the same rules. All of them need to be converted into numbers. For instance, if you have the date January 1, 2022, written down, you should update it to 01/01/2022.

Clear Formatting
Data that is overly structured will be inaccessible to machine learning algorithms. If you are compiling information from several resources, you may encounter a wide variety of file types. Inconsistencies and errors in your data are possible results.

Any pre-existing formatting should be removed before you begin working on your documents. This is typically a straightforward operation; programs like Excel and Google Sheets include a handy standardization feature.

Fix Errors
You’ll want to eliminate all mistakes from your data with extreme caution. Simple errors can cause you to lose out on important insights hidden in your data. Performing a simple spell check can help avoid some of these instances.

Data like email addresses might be rendered useless if they contain typos or unnecessary punctuation. It may also cause you to send email newsletters to those who have not requested them. Inconsistencies in formatting are another common source of error.

A column containing just US dollar amounts, for instance, would require a conversion of all other currency types into US dollars to maintain a uniform standard currency. This also holds for any other unit of measurement, be it grams, ounces, or anything else.

Language Translation
You’ll want everything to be written in the same language so that your data is consistent. Also, most data analysis software is limited in its ability to process many languages because of the monolingual nature of the Natural Language Processing (NLP) models upon which it is based. In that case, you’ll have to do a complete translation into a single language.

Handle Missing Values
There are two possible approaches to dealing with missing values. You can either input the missing data or eliminate the observations that contain this missing value. Your decision should be guided by your analysis objectives and your intended use of the data.

The data may lose some valuable insights if you just eliminate the missing value. You probably have your reasons for wanting to retrieve this data in mind. It may be preferable to fill in the blanks by determining what should be entered into the relevant fields. If you don’t recognize it, you can always substitute “missing.” If it’s a number, just type “0″ into the blank. However, if too many values are missing to be useful, the entire section should be eliminated.

Your career, like any journey, has a beginning, an end and a
direction. For many people, the present direction of the
career is probably not a result of entirely their own
choices. If, for some reason, you are not happy with the
direction of your career, there is a way out: Take charge of
your career and change its direction.

1. Know yourself

Has it happened with you that after desperately looking for
something (e.g., keys) all over the place, you eventually
found it right in your pocket or drawer?

That’s exactly the case with finding a new career direction.
Usually, we try to search for a new career direction by
looking all around, for example, at hot jobs, emerging
fields, prestigious companies, friend’s career, what’s safe
and so on. Ironically, we fail to look for the answer where
it actually lies: inside us.

The secret of finding the right career direction is not to
look outside but to look inside. Know yourself and you will
automatically know the right direction for your career.

2. Dig deeper

Most people define themselves is terms of what they write in
their resumes. That’s just the tip of the iceberg. To really
know yourself, dig deeper and uncover your:

(a) Strengths
(b) Personality
(c) Values
(d) Interests

(a) Strengths

Your strength is what you do well and enjoy doing it. We
never fail to admire strengths in top athletes, painters,
writers, leaders but fail to ask “What is my strength?”

Strengths have a solid connection with a person’s career.
According to Peter Drucker, a person can only perform from
his strength. In other words, mediocrity is guaranteed if we
fail to use our strengths. So know your strengths and get
into a career that allows you to leverage your strengths to
the maximum.

Discover your strengths by asking:

- What am I good at and also enjoy doing?
- What makes me feel energized?
- What comes naturally and easily to me?

(b) Personality

Personality is the sum total of a person’s behavioral,
temperamental and emotional traits. For example, some people
are by nature extrovert and enjoy meeting other people. But
some people are born introvert and feel more comfortable
when left alone.

Studies show a direct link between a person’s personality
and his career. Indeed, if you are an extrovert person, you
would do well in roles such as sales, marketing, public
relations. But an introvert person would be better off in
roles that do not require public dealing.

To know your personality in detail and its implications on
your career, appear at personality tests such as Myers
Briggs Test Instrument (MBTI).

(c) Values

Values are what you consider important and valuable. Values
differ from person to person and can range from things like
money, prestige and power to more subtle things like
respect, harmony and independence.

Your values hint towards the kind of work that will suit
you. For example, if you value “achievement, “you would do
well in roles that regularly throw challenges at you.
Someone else, however, may value “helping others” and,
therefore, would do well in occupations that provide an
opportunity to serve others.

To know your values, ask yourself what is important to you,
make a list and prioritize the items. You can also use value
inventories on the Internet to identify your values.

(d) Interests

Should the work be interesting? Yes, for an important
reason: If your work arouses your interest, you are going
to do well. History shows that great achievers always pursued
what fascinated them. Akio Morita shunned the option of joining
the family business of sake brewing to pursue what he was
interested in: an electronics start-up. And he created Sony.

Doing the work that interests you can have a lasting impact
on your career. To uncover your interests, find out what
fascinates you and draws your attention.

Knowing your strengths, personality, values and interests is
like having a compass with its needle pointing towards the
right direction for your career.
