ICSE Class 6 Maths, Unit 6: Data Handling

What this unit aims at

This theme focusses on building on and reinforcing children’s understanding of numbers, they begin to develop their ability to think statistically. Children recognize that a data distribution may not have a definite centre and that different ways to measure centre yield different values. The median measures centre in the sense that it is roughly the middle value. The mean measures centre in the sense that it is the value that each data point would take on if the total of the data values were redistributed equally, and also in the sense that it is a balance point.

Your child should be able to

• understand the use of organizing data
• represent data through pictograph, bar graph
• identify patterns in numbers and shapes
• identify daily life situations in which the information is required to be properly arranged
• explore different ways to organise and represent data
• appreciate the need for finding a representative value for given data
• find mean and median of data having not more than ten observations

Key concepts in this unit

• Collection of data to examine a hypothesis
• Collection and organisation of data - examples of organising it in tally bars and a table.
• Pictograph- Need for scaling in pictographs interpretation & construction of pictograph
• Construction of bar graphs for given data interpreting bar graphs.
• Mean and median of data not having more than ten observations
