Statistics for Class 10 CBSE - MathematicsLet's Tute
This is a booklet on Statistics for the students of CBSE Class 10.
Statistics plays an important role in different fields as it helps in understanding the situations and making predictions for future. All this prediction and strategies are purely based on observations and availability of data.
This Booklet specially designed on Statistics will help you in learning the following topics:
· Measures of the Central tendency for grouped and ungrouped data.
1) Mean
2) Mode
3) Median also
· Graphical representation of cumulative frequency more than type-ogive and less than type-ogive.
To give you an overview of this chapter:
It starts with formulae and steps to calculate mean, mode and median for grouped and ungrouped data.
It provides related MCQs with their answers,
a set of solved problems with their logical solutions,
Some question for practice with their final answers given at the end and
Some important points/facts about the topic are also covered.
What more if you ask?
Well, we are providing this special feature where you can view our explanatory videos just by scanning the QR which will take you directly to our YouTube page.
Auguste Comte was a French philosopher considered the founder of the discipline of sociology. He proposed studying society scientifically through observation and classification of data. Comte believed that human thought progressed through three stages - theological, metaphysical, and positive. In the positive stage, which began around the 19th century, observation took precedence over imagination and the concept of God was replaced by seeking to understand causal relationships through empirical investigation and data. Comte coined the term "sociology" and emphasized the study of social progress and order through his concepts of social statics and dynamics. He developed the "Law of Three Stages" to describe the necessary and progressive evolution of human thought.
The document discusses Auguste Comte's theory of the three stages of social evolution: the theological stage, the metaphysical stage, and the positivist stage. It explains each stage in detail, from fetishism and polytheism in the theological stage to the emphasis on scientific observation and industry in the positivist stage. The document also discusses how Comte's philosophy of positivism influenced thinkers in Latin America and Brazil in particular in the 19th century.
This document discusses diagrammatic presentations of data, which use geometric techniques like bar diagrams, pie charts, and cartograms to visually present numerical information. The main advantages of these diagrams are that they are attractive, easy to remember and understand, simplify complex data, and help make comparisons. There are one-dimensional, two-dimensional, and three-dimensional diagrams. Examples provided include line graphs, bar graphs, sub-divided bar graphs, rectangular diagrams, and pie charts. Pie charts in particular can be used to show percentages and proportional relationships between parts of a whole.
The document discusses different forms of equations for straight lines, including:
- Point-slope form, which defines a line through a known point with a given slope
- Slope-intercept form, which defines a line with a given slope and y-intercept
- Normal form, which defines a line based on its perpendicular distance from the origin and the angle it forms with the x-axis
- General form, which is the standard Ax + By + C = 0 equation for a line
It also covers how to find the distance from a point to a line, and how parallel and perpendicular lines can be identified based on the coefficients in their equations.
BASICS OF ALGEBRIC EXPRESSION
REVISION OF CONCEPTS
DEGREE, ZEROS
MULTIPLATION & DIVISION OF EXPRESSIONS
FACTORISATION
GEOMETRIAL INTERPRETATION OF POLYNOMIALS
VERIFICATION OF ZEROS & COEFFICIENTS OF A POLYNOMIAL
OBTAINING POLYNOMIAL FROM SUM AND PRODUCT OF ZEROS
