Medical Statistics Simplified - Data Organization And Visualization For Quantitative Variables
This video is the second part of the data organization and visualization topic of medical statistics made easy by Edusurg Clinics.
Data organization and visualization are important steps in analyzing quantitative variables. Here are some techniques for organizing and visualizing quantitative data:
Frequency distribution: This technique involves grouping data into intervals or bins and counting the number of observations that fall within each interval. A frequency table can be created to show the frequency of each interval.
Cumulative frequency is specifically useful in this data type.
Histogram: A histogram is a graphical representation of a frequency distribution. It is a bar chart where the bars represent the frequency of each interval.
The video highlights the differences between a bar chart and histogram and a Frequency curve and ogive as well.
