Organisation of Data
The process of arranging raw data into homogeneous classes or groups based on common characteristics to make it understandable and ready for analysis.
Classification of Data
The grouping of collected data into classes or categories according to similarities, which can be chronological, geographical, qualitative, or quantitative.
Variables (Discrete and Continuous)
Characteristics that can take different numerical values; discrete variables take exact whole values, while continuous variables can take any value within a specific range.
Frequency Distribution
A tabular summary of data showing the frequency (count) of items in each of several non-overlapping classes or categories.
Inclusive and Exclusive Methods
Methods of forming class intervals where the exclusive method includes the lower limit but excludes the upper limit, while the inclusive method includes both limits.

Frequently Asked Questions
What is the difference between raw data and organized data?
Raw data is unorganized information collected directly from the field, whereas organized data is systematically arranged in rows and columns or tables for easy analysis.
When should we use the inclusive method instead of the exclusive method?
The inclusive method is used when data consists of discrete values (like whole numbers of students or items) where the upper limit of one class does not overlap with the lower limit of the next.
How do you calculate the mid-point of a class interval?
You add the lower limit and the upper limit of the class interval and divide the sum by 2.
