What does the number over another number notation mean in Statistics? What is meant by the term significance in statistics? What is a statistical notation? Here are 8 numbers: 3, 5, 7, 9, 15, 5, 7, 1. Determine the mean. Explain what is the difference between Math 222 and Statistic ...
The ONS believes that the RPI isn’t a great statistic, because it is likely to considerably overstate or at times understate inflation, and it discourages its use. However, it still calculates and publishes the RPI monthly, because it’s used in long-term contracts and index-linked gilts....

the number of clusters is not known in advance. Various methods can be used to estimate the optimal number of clusters, such as the elbow method, silhouette analysis, or gap statistic. These methods evaluate clustering results for different numbers of clusters and provide insights into the optimal...
For k-means clustering, select the number of clusters, then the clustering algorithm iteratively estimates the cluster means and assigns each case to the cluster for which its distance to the cluster mean is the smallest. For hierarchical clustering, choose a statistic that quantifies how far apa...
