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.} CARTESIAN PLANE X axis: Horizontal scale Abscissa Y axis: Vertical scale Ordinate PROBABILITY: CHANCE OF SOMETHING = ...
