Raw Data
The initial, unorganized collection of numbers or information gathered directly from a survey or observation before any processing is done.
Frequency
The number of times a particular observation or value occurs in a given set of data.
Tally Marks

Board Exam Info
In the Maharashtra (MSBSHSE) Class 6 Mathematics examinations, this chapter typically carries around 4 to 6 marks. Common question types include creating a frequency distribution table using tally marks from raw data, drawing a bar graph or pictograph based on given statistical values, and answering questions by reading and interpreting data from a given graph.
Frequently Asked Questions
How do I group tally marks correctly?
You draw vertical lines for each count, and for the fifth count, you draw a slanted line across the first four lines to make a bundle of five (HI).
Why is a scale important in a pictograph or bar graph?
A scale helps us represent large numbers using smaller, manageable units (e.g., 1 picture = 10 students), making the graph compact and easy to read.
Do I need to use graph paper for bar graphs in Class 6 exams?
Yes, standard graph paper is usually required for drawing bar graphs accurately, ensuring proper spacing and equal bar widths.
