Tally se bar graph: data ka chitra
Class ke 20 bachche school kaise aate hain — paidal, cycle, bus ya auto? Ek nazar mein kaise dikhaoge?
Socho pehle… phir dekho jawab
Pehle tally se gino, phir har jawab ke liye ek khamba (bar) banao — jitni ginti, utna ooncha. Ise bar graph kehte hain. Sabse ooncha khamba turant dikh jaata hai.
Ravi ne class mein survey kiya: paidal 8, cycle 5, bus 4, auto 3 — kul 20. Ek dost bola, 'Cycle ka khamba bada bana do, mujhe cycle pasand hai!' Ravi ne muskura kar kaha, 'Graph wahi dikhayega jo sach hai,' aur har khamba sahi oonchai ka banaya.
Cause-effect: bar graph mein har khamba ek hi chaudai ka hota hai, sirf oonchai badalti hai, aur oonchai shunya se naapi jaati hai. Isliye aankh turant tulna kar leti hai — paidal wala khamba sabse ooncha!
Scale: jab number bade hon, toh '1 khaana = 2 bachche' jaisa scale rakhte hain. Yeh kahan chhupa hai? TV par mausam aur cricket ke chitron mein, aur school ke result ke chart mein — bar graph har jagah hai.
Ghar pe try karo
Ghar aur padosi ke 10 logon se poochho: 'Tumhara pasandeeda mausam kaun sa hai — garmi, sardi ya baarish?' Tally banao, phir copy ke khaanon mein bar graph banao (1 khaana = 1 jawab).
Wow!
Ek hi nazar mein 20 logon ki baat samjha dena — yahi bar graph ka jaadu hai!
Mummy-Papa ke liye
Aaj bachche ke 10 logon wale survey mein madad kijiye aur uska bar graph dekh kar poochhiye: 'Sabse ooncha khamba kya batata hai?'
