Important Topics for RS Aggarwal Solution for Class 9 Maths Chapter 16

Instasolv solution will help you to understand the basics definition and characteristics of statistics. They are as follows:

  • Statistics is the science which deals with the collection, presentation, analysis, and interpretation of numerical data.
  • Numerical records alone represent data.
  • Qualitative characteristics like intelligence, poverty, etc., which are unable to be measured numerically, do not form data.
  • Data are aggregates of different facts. An observation never forms data.
  • Data accrued for an exact purpose may not be acceptable for another purpose.
  •  Data in specific experiments are comparable.

Highlighting facts and comparison of the primary and secondary data:

  • Primary statistics: The data accumulated through the investigator himself with a definite plan in mind are called primary information. These statistics are, therefore, rather dependable and applicable.
  •  Secondary statistics: The facts amassed using someone, apart from the investigator, are referred to as secondary information. Secondary facts need to be carefully used since they may be collected with a reason specific from that of the investigator and won’t be fully applicable to the investigation.

Some important definitions related to this chapter are as follows:

  • Any character when capable of taking several distinct values is known as a variant.
  • Each organization into which the raw data is condensed is known as a class interval.
  •  Class size is defined as the distinction among both the true upper and the lower limit within a category.
  • Classmark is defined as the mean of upper limit and lower limit.
  •  Each class is bounded by two figures that are known as called class limits.
  • The upper and lower limits of a class are respectively known as the true upper limit and true lower limit.
  • The wide variety of instances an observation occurs in a category is known as the frequency.
  • The cumulative frequency similar to a class is the sum of all frequencies along with that class.
