Amcangyfrif y Cymedr a Grwp Moddol ar Gyfer Data Wedi’i Grwpio

Amcangyfrif y Cymedr a Grwp Moddol ar Gyfer Data Wedi’i Grwpio. Data wedi’i grwpio. Agorwyd pum deg o fagiau losin. Dyma gofnod o faint oedd ym mhob bag:. Pa un yw’r grwp moddol?. Mae’r gwybodaeth isod yn dangos taldra 60 o bobl i’r cm agosaf. Data wedi’i grwpio.

  1. Amcangyfrif y Cymedr a Grwp Moddol ar Gyfer Data Wedi’i Grwpio

  2. Data wedi’i grwpio • Agorwyd pum deg o fagiau losin. Dyma gofnod o faint oedd ym mhob bag: Pa un yw’r grwp moddol?

  3. Mae’r gwybodaeth isod yn dangos taldra 60 o bobl i’r cm agosaf

  4. Data wedi’i grwpio • Agorwyd pum deg o fagiau losin. Dyma gofnod o faint oedd ym mhob bag: Pa un yw’r grwp moddol?

  5. Data wedi’i grwpio • Agorwyd pum deg o fagiau losin. Dyma gofnod o faint oedd ym mhob bag: Amcangyfrif o’r cymedr = 120 20 1455 ÷ 50 25 350 = 29.1 30 480 35 385 40 120 Cyfanswm (∑ f) = Amlder 50 Cyfanswm (∑fx) = 1455

  6. Mae’r gwybodaeth isod yn dangos taldra 60 o bobl i’r cm agosaf Beth yw’r grwp moddol ac amcangyfrif o’r cymedr?

  7. Mae’r gwybodaeth isod yn dangos taldra 60 o bobl i’r cm agosaf 588 Amcangyfrif o’r cymedr = 147 152 2432 9470 ÷ 60 157 2983 = 157.83333 162 = 157.83 cm i 2 lle degol 1782 167 1169 172 516 Cyfanswm (∑ f) = Amlder 60 Cyfanswm (∑fx) = 9470
