  • It gathers and organizes information from many sources to offer insightful business analysis.
  • There are various sorts of data warehouses that exist.
Data lakes:

  • Clean data improves the performance of the model.
  • It keeps analytical results from being biased.
Q19. Define Pivot table and its uses?

Answer: The pivot table is one of the fundamental instruments for data analysis. This tool in Microsoft Excel allows you to swiftly summarize huge datasets. It allows us to convert rows into columns and columns into rows. Moreover, it allows grouping based on any field (column) and performing sophisticated computations on them. You may create a report by just dragging and dropping the rows and columns headers, making it an incredibly user-friendly program. There are four distinct sections found in pivot tables:

  • Value Area: Reports on values are located here.
  • Row Area: The headers to the left of the values make up the row areas.
  • Column area: The column area consists of the heads that are situated above the values area.
  • Filter Area: This filter allows you to explore the data set more deeply.
Q20. Describe the idea of data normalization?

Answer:

  • Features are scaled to a common range using data normalization.
  • It lessens data variance, which improves model performance.
  • Z-score normalization and min-max scaling are two techniques.
  • Normalization guarantees that no characteristic takes center stage.
  • Distance-based algorithms require it.
