Information About Data Cleaning And Data Services

What Is Dirty Data?

Dirty data refers to any data that must be altered or modified before it can be analysed. There are several types of dirty data:
Incomplete data: For example, a spreadsheet that contains missing values. This could be a problem for your analysis. Data for both customer age and monthly purchases is required if you want to analyze the relationship between these variables. You’re dealing incomplete data if you don’t have the customer ages.
Duplicate data is records that appear in the same dataset twice or more than once. If you combine data from different sources or databases, this can happen.
Inconsistent and inaccurate data – Data that is out of date or has structural errors like typos, inconsistent capitalization or irregular naming conventions. Let’s say you have a data set that contains student test scores. Some are categorized as Pass or Fail, while others are categorized as P or F. The labels are the same, but the naming convention makes it difficult to distinguish between them.
There is much to do before you can begin the analysis phase of data analytics. The data analytics process can take up to two-thirds of its time to clean “dirty” data. This is data that must be edited, worked upon, or modified in any other way before it can be used for analysis.
Data analysts may discover outliers in “dirty” data during the cleaning phase. This leads to either removing them completely or using another method. So, the question is: What is an outlier?

What Is an Outlier?

  • Outliers in data analytics are values that differ significantly from other datasets. They can be either much larger or smaller. Outliers can indicate variabilities in measurements, experimental errors or a novelty. A real-world example shows that giraffes average about 16 feet in height. Recent discoveries have revealed that two giraffes are 9 and 8.5 feet tall. These two giraffes are considered to be outliers compared to the rest of the giraffe population.
  • Outliers can lead to anomalies in data analysis results. These outliers can cause problems in data analysis and may need to be addressed.
    Two main reasons outliers should be given special attention in data analytics are:
    Analyses may be affected by outliers
    An analyst may need to know about outliers or their behavior in order to complete an analysis.
