maths performance task part 3

Some things i come across at home that i find statistical computation or graphical representation are the electricity usage, they are relevant to me and my parents as we can keep track of the amount of electricity we use and try to decrease the usage.Other statistical computation or graphical representation that i find at home are line graphs keeping track of the amount of money spent, this graph can see whether we are over spending . Statistical computation or graphical representation can also use to show data on the number taxi at each taxi stand, this can help to improve the speed of picking up commuters at taxi stand. Newspapers articles that use statistics to show information are the stock market, the graph keeps track of the stock.Other articles that also use statistic to show information are the number of robberies in singapore, the graph can show us if the number of robberies are decreasing or increasing.If statistics are not presented properly, they can mislead people , examples are graphs having big intervals may misled people thinking this brand is far more popular than the other brand
