Information About Data Cleaning

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Inconsistent and inaccurate data – Data that is out of date or has structural errors like typos, inconsistent capitalization or irregular naming conventions.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.

Gresham, OR, is the fourth largest city in Oregon, located in east Multnomah County. It is known for its stunning views of Mount Hood and Multnomah Falls. Since the city’s population is small, this mid-sized city will give you the feel of a small town with all the modern amenities.

History

The area was first settled back in 1851 by Jackson and James Powell and was known by a few other names like Powell’s Valley and Camp Ground. However, the name got traction only in 1884. During this time, it was the territory of Chinookan people who hunted in Johnson Creek and fished in Johnson Creek. They were skilled in producing tools, clothing, canoes, and basketry.
The pioneer settlers were attracted by the huge amount of land beside the river. They started to clear the forests to make farming possible. It was during the 1860s that the first lumber mills were set up, and families started transitioning to farming. The favorable climate and the nutrient-rich soil were ideal for growing potatoes, grain, corn, hops, and lettuce. Later, in the 1910s, farmers grew strawberries, filberts, and Cuthbert raspberries.
After the arrival of the Springwater Division Rail Line in 1903, Gresham saw population growth with an increase in accessibility to other major towns for business. The city’s first mayor was elected in 1904, and the city was officially incorporated on Feb 11, 1905. The Interstate Highway system in the 1950s and 1960s made this sleepy farmland a major suburb.

Climate

Gresham has a warm and temperate climate as it is located in the Northern Hemisphere. The city never gets too hot or too cold, and the locals take full advantage of it.
