Introductory Statistics Quiz 23

The post is about an Online introductory Statistics Quiz. Test your Basic Statistics knowledge on:
✅ Data types (quantitative vs. categorical)
✅ Measures of central tendency (mean, median, mode)
✅ Skewness & outliers (left vs. right skew, detecting extremes)
✅ Relationships between measures (how mean/median/mode shift in different distributions)
✅ Conversion and Normalization of data

Let us start with the Online Introductory Statistics Quiz now.
