Data ko graph mein kaise dikhayein?

Short mein jawab

Data ko tasveer mein dikhaane se uske pattern ubhar aate hain. Clustered bar graph mein har category ke liye do ya zyaada groups ke bars saath saath bante hain, aur rangon ki key hoti hai; har cluster mein do bars hon to ye double bar graph hai. Graph do step mein padho: kya diya hai pehchaano, phir nateeja nikaalo.

Data ki tasveer

Data aksar table se zyaada tasveer mein samajh aata hai. Data ko tasveer mein badalna data visualisation kehlaata hai. Class 6 mein tumne ek data set ke liye bar graph banaaye the. Ye chapter do ya zyaada sets ko ek hi graph pe rakhta hai taaki unhe ek nazar mein compare kiya ja sake.

Columns ko saath laana

Yahapur aur Wahapur ke pyaaz ke daam do alag column graphs mein bhi ban sakte hain, ek har shehar ka. Par shehron ko mahine waar compare karna ho to har mahine ke do bars bagal bagal mein khade karna aasaan hai. Ye clustered column graph hai, aur har cluster mein do columns hain isliye ye double column graph bhi hai. Dono shehron ko alag rang milte hain, jo key mein samjhaaye jaate hain.

Yahan scale 1 unit = ₹10 hai. Dono bars ki oonchaai compare karte hi pata chal jaata hai ki har mahine kaunsa shehar mehenga tha, aur gridlines se andaaza lagta hai ki kitna. Bars ke andar dots ya tirchhi lines un logon ki madad karti hain jinhe rang pehchaanne mein dikkat hoti hai, aur black-and-white print mein bhi kaam aati hain. Bars khade hon ya leti hui, aise graph ko clustered bar graph bhi kehte hain.

Graph padhne ke do step

Step 1, kya diya hai pehchaano; step 2, usse nateeja nikaalo
Graph padhne ke do step

Graph mein bahut jaankaari hoti hai, isliye book do step sujhaati hai. Uska graph lo jo 2021, 2022 aur 2023 mein SpaceX, CASC, Roscosmos aur ISRO jaisi sansthaon ke rocket launch dikhata hai.

  1. Kya diya hai pehchaano. Har sanstha ke teen bars hain, har saal ka ek, aur scale 1 unit = 20 rocket hai. “Other” waala bar kai chhoti sansthaon ko milaata hai taaki graph chhota rahe. Pyaaz waale graph ke mahinon ki tarah yahan sansthaon ka kram maayne nahi rakhta.
  2. Nateeja nikaalo. SpaceX ne 2021 se 2022 mein launch lagbhag dugne kiye aur 2023 mein kareeb 35 aur jode. Arianespace ne har saal kam launch kiye. USA, China aur Russia ki sansthaon ne sabse zyaada launch kiye.

Inhi steps se statements bhi jaanch sakte ho. “Sirf USA ki ek sanstha ne ek saal mein 50 se zyaada rocket launch kiye” sahi hai, kyunki sirf SpaceX 50 paar karti hai. “Har sanstha ne har saal pichhle saal se zyaada rocket launch kiye” galat hai.

Ek hi samay garmi aur sardi

Helsinki aur Wellington mein har mahine roz ki average daylight ke ghante
Roz ki daylight ke ghante

Do shehron ke har mahine ke daylight ghanton ko us mahine ke dinon se bhaag dene pe roz ki average daylight milti hai. 1 unit = 5 ghante waale double bar graph pe City 1 June mein lagbhag 18.8 ghante roz (564 ghante ÷ 30 din) tak pahunchta hai aur December mein lagbhag 6 pe aa jaata hai, jabki City 2 ulta karta hai, December mein lagbhag 15 ghante se June mein 9 tak. City 1 Northern Hemisphere ka Helsinki hai aur City 2 Southern ka Wellington, isliye June ek mein garmi hai aur doosre mein sardi. Dono Equator se door hain, isliye unki daylight itni badalti hai.

Ek minute mein match

Cricket ka “runs per over” graph poora match ek tasveer mein dikhata hai: neeche overs, side mein 1 unit = 5 run ke saath run, har over ka ek neela aur ek laal bar, aur jahan wicket gira wahan chhote gole. Sabse zyaada ya sabse kam run waala over pal bhar mein mil jaata hai. Kuch cheezein phir bhi mushkil hain; jaise target jaanne ke liye pehle batting karne waali team ke saare bars jodne padte hain.

Scale chunna

Jab khud graph banaao, sabse badi value se scale chuno. 43 °C tak ke Jodhpur ke taapmaan ke liye 1 unit = 4 °C theek hai; zyaada se zyaada 13 students ki superpower pasand ke liye 1 unit = 2 students.

Ye kyun zaroori hai

Khabron, mausam ki report aur khel ki coverage mein graph bhare hote hain. Unhe do step mein padhne se samajh aata hai ki wo kya dikhate hain aur kya chhod dete hain. Data ko numbers se samjhaana mean (average) kaise nikalein? aur median aur outliers mein seekho. Textbook ke sawaalon ke jawab Part 2 Chapter 5 ke NCERT solutions mein hain; poore Part 2 Chapter 5 ke notes dekho.

Practice karo

  1. Pyaaz ke daam ke double bar graph mein har cluster ke do bars kya dikhate hain?

    1. (a) Ek shehar ke do mahine
    2. (b) Ek hi mahine mein dono shehron ke daam
    3. (c) Sabse ooncha aur sabse neecha daam

    Jawab dekho

    Jawab: (b) Ek hi mahine mein dono shehron ke daam

  2. Graph ka scale 1 unit = 4 °C hai. 28 °C ka bar kitna lamba hoga?

    2. (b) 7 units
    3. (c) 28 units
    4. (d) 112 units
    Jawab dekho

    Jawab: (b) 7 units

  3. Do shehron ki mahine waar baarish compare karne ke liye kaunsa graph theek hai?

    1. (a) Akela bar graph
    2. (b) Clustered (double) bar graph
    3. (c) Ek shehar ka dot plot
    4. (d) Sirf total ki table
    Jawab dekho

    Jawab: (b) Clustered (double) bar graph

  4. Double bar graph dikhata hai ki teen mahinon mein Class A ne 12, 15 aur 9 kitaabein padhi aur Class B ne 10, 15 aur 14. Dono classes ko mahine waar compare karo.

    Jawab dekho

    Jawab: Har jodi ke bars compare karo: mahine 1 mein Class A ne 2 zyaada padhi, mahine 2 mein dono ne 15, aur mahine 3 mein Class B ne 14 − 9 = 5 zyaada. Teen mahinon mein Class B ne 39 aur Class A ne 36 kitaabein padhi.

  5. Kuch double bar graphs mein bars ke andar dots ya tirchhi lines kyun hoti hain?

    Jawab dekho

    Jawab: Taaki jo log rang aasaani se nahi pehchaan paate, ya jo black-and-white print dekhte hain, wo bhi dono groups ko alag pehchaan sakein.

Students ke sawal

Clustered bar graph kya hai?

Aisa bar graph jisme har category ke liye do ya zyaada groups ke bars saath saath khade hote hain, jaise har mahine ke liye do shehron ke pyaaz ke daam. Key batati hai ki kaunsa rang kaunsa group hai. Cluster mein do bars hon to ise double bar graph bhi kehte hain.

Bar graph ka scale kaise chunein?

Sabse badi value dekho aur aisa step chuno jisse graph theek size ka rahe aur numbers aasaan hon. 43 °C tak ke taapmaan ke liye 1 unit = 4 °C theek hai, to axis pe 11 units chahiye; 13 students tak ki ginti ke liye 1 unit = 2 students.

Graph kaise padhna chahiye?

Do step mein. Pehle pehchaano kya diya hai: title, har axis kya dikhata hai, scale, key aur pattern. Phir nateeja nikaalo: bars compare karo, badhna aur ghatna batao, scale se values ka andaaza lagao, aur jaancho ki data sach mein kaunse statement ko sahi thehraata hai.
