Data Handling

-

Scatter are used to see correlation of between two sets of discrete data 


Strong positive correlation - the pionts lie very close to each other's and if x increase then y also increases

Weak positive correlation - the point lie a bit apart from each other and if x increases then y tends to increase


Strong negative - the poitns lie very close to each other and if x increase then y decreases 

Weak negative - the points lie a bit apart from each other and if x increase then y tends to decrease 


Mean - sum of all values / total number of values 

Median - middle values if two middle values are present calculate  average 

Mode - most frequent value  

Range - highest value - lowest value

Win Friends and Influence People

Few Key Principles from How to Win Friends and Influence People  Listen to others In the hustle life many people are having troubles, many people lives unhappy life, many people don't have anyone to listen to them.

BE A GOOD LISTENER ENCOURAGE OTHERS TO TALK  The law of wining someone is: Always make the other person feel important.  (desire to be important is the deepest urge in human nature) The true and genuine app...

Volume and Surface Area of Prisms

 Volume: The Volume of prisms can be calculated by multiplying area of cross-section and length. formula - area of cross-section * length  Area of cross-section: it the area where you via the shape and the shape and area remains same    Different formulas are used for different area cross-section, here are few examples: Area of cross-section of a cylinder:  π*r^2 Volume of a cylinder: Area of cross-section of a cylinder * length where:  r=radius Surface Area: Surface area of a 2-d shape is adding area of it's all sides. But there are formulas for few: surface area of a cylinder: =area of circle*2 + area of rectangle                                             =2πr^2 + 2πrh  here: length- 2πr

Heat Energy Transfers

-
What is Heat? Heat is the transfer of kinetic energy from one medium or object to another, or from an energy source to a medium or object. Such energy transfer can occur in three ways: radiation, conduction, and convection. Measuring Heat Energy There are many different ways of measuring heat energy, for example it can be measured by thermometer- the kinetic energy from a substance is passed in the thermometer, due to which the atoms or molecules from which the mercury(liquid inside thermometer) moves faster. This causes the liquid to expand. How Heat Energy Travels As I mentioned earlier that heat energy can travel via ways- radiation, conduction, convection. Conduction In conduction, the kinetic energy is travelled from particle to particle. Example- heating water. Conduction generally occurs in solid or liquid, but this can't occur in gas as the particles in gas are far from each other, so they do not affect the movement of each other. Convection In convection, the ...
