Handling Duplicate data from Dataset

Handling duplicate data is crucial in any machine learning model, just as removing null data is.

Duplicate entries can significantly impact the accuracy of statistical analysis, leading to misleading results.

For example, counting the same customer twice in a sales report can inflate total sales figures, skewing calculations like mean, median, and standard deviation.

Moreover, duplicate data can distort trends and patterns, making it challenging to derive accurate insights from your analysis.

Repetitive entries, such as recording the same survey response multiple times, can overemphasize certain opinions, affecting the overall conclusions drawn.

Additionally, dealing with duplicate data incurs unnecessary storage space usage, especially in extensive datasets. Processing repeated information also prolongs computational time, thereby slowing down the analysis process.

Furthermore, the presence of duplicate data threatens the integrity of your dataset, casting doubt on the accuracy of your findings. Therefore, ensuring data cleanliness and error-free records is essential before embarking on any analysis.

Maintaining data integrity by addressing duplicate entries is a fundamental step in enhancing the reliability and accuracy of machine learning models.
