Seekho

Tumhari teacher do puraane doston se mil rahi hain: ek 5 feet lamba, ek 6 feet. Zyaadatar log andaaza lagaate hain ki chhota wala mahila hai. Galat ho sakte hain, par bahut logon ka anubhav kehta hai ki purush aksar lambe hote hain. Kai avlokanon ke pattern se tark statistical soch hai.

"Hamare gaon ki aabaadi das saal mein lagbhag 100 ghati." "Mujhe cycle se ghar pahunchne mein lagbhag 15 minute lagte hain." Ye statistical kathan hain: numbers, anupaat ya anumaan par aadhaarit daave, badalte data se bane.

Statistical sawaal ka jawaab badalte data ikattha karke milta hai. "Hamare school ke Class 7 ke bachche kitne lambe hain?" aisa hai: lambaai alag-alag. "Kabir kitna lamba hai?" nahi: ek hi jawaab. Na hi ek vyakti se poochha "Kya tumhe padhna pasand hai?"

Statistics data ikattha karne, sajaane, vishleshan, vyakhya aur prastuti ka adhyayan hai. Is chapter mein data ko ek number se saar mein, dot plot aur double bar graph se chitra mein dikhaayenge, aur data jaasoos banenge.
