Options:

  1. 50
  2. 40
  3. 60
  4. 30

Correct Answer: 50

Solution: 

If K=4 and there are 200 points, on average, each cluster will have 200/4 = 50 points assigned to it.

Questions & Step-by-Step Solutions

If a dataset has 200 points and you apply K-means clustering with K=4, how many points will be assigned to each cluster on average?
Correct Answer: 50
  • Step 1: Identify the total number of points in the dataset, which is 200.
  • Step 2: Identify the number of clusters you want to create, which is K=4.
  • Step 3: To find the average number of points per cluster, divide the total number of points by the number of clusters: 200 points ÷ 4 clusters.
  • Step 4: Calculate the result: 200 ÷ 4 = 50.
  • Step 5: Conclude that on average, each cluster will have 50 points assigned to it.
  • K-means Clustering – A method of partitioning a dataset into K distinct clusters based on feature similarity.
  • Average Distribution – Understanding how to calculate the average number of points per cluster when dividing a total number of points by the number of clusters.
