REVISON: MATH- DATA HANDLING

 LESSON:

*Data Handling

*lines and angles

*linear equation

*triangle and its properties

*comparing quantities

*area and perimeter

DATA HANDLING:

FREQUENCY: Number of times a particular observation occurs is called its Frequency.

ARITHMETIC MEAN: Average of data. 

      Mean= sum of all observation

               Total number of observation

RANGE: Highest observation– Lowest Observation.

MEDIAN: Middle Number , arranged is ascending or descending order.

MODE: The number which is most repeated or frequent in a set of data.{more than one mode can be also there.}

OUTLIER OF THE DATA: Extreme different from the set of other numbers in a data, It can be very high or very low number. {not necessary to have for all set of data.}

PROBABILITY:

CHANCE OF SOMETHING =

                     Number of successful outcomes

                     Number of Possible outcomes

  

         Probability of event will not be:

*Will not be less than 0.
