Kifaa cha Kuhesabu Watu

Tumia vipimo tofauti - tofauti kama uwiano wa kawaida wa kasoro za kawaida ili kuonyesha kwamba mtu anapaswa kubadilika.

Kanuni zilizotengwa zenye vituo au nafasi mbalimbali.

Kuhusu kifaa hiki cha kupigia hesabu

The coefficient of variation (CV) expresses the standard deviation as a percentage of the mean, giving a unit-free measure of relative spread. Because it is scale-independent, the CV lets you compare the variability of data sets that have very different means or units — you can put the consistency of a set of body weights next to a set of exam scores even though they share no units.

The formula is simply CV = (standard deviation ÷ mean) × 100%. This calculator uses the sample or population standard deviation you choose, divides it by the mean of the data and flags whether the relative variability is low, moderate or high (below about 15%, between 15% and 30%, or above 30% here).

Worked example: for 10, 12, 14, 16, 18 the mean is 14 and the sample standard deviation is about 3.16, so the coefficient of variation is 3.16 ÷ 14 × 100% ≈ 22.6% — moderate relative variability. The CV is widely used in finance to compare investment risk per unit of return and in the lab to judge the precision of repeated measurements.

Maswali yaliyoulizwa mara nyingi

Ni nini chanzo cha juu cha tofauti - tofauti?

Hakuna upunguzaji wa kila mahali, lakini CV chini ya asilimia 15 mara nyingi huonwa kuwa ni ya chini (tofauti) na zaidi ya asilimia 30 juu kwa kulinganisha.

Ni wakati gani ambapo muundo wa aina mbalimbali hausaidii?

CV haitegemeki wakati ambapo mwisho uko karibu, kwa sababu kugawanya kwa namna ndogo sana hufanya lilipuke, na si jambo la maana kwa data zenye thamani hasi au data zisizo na sufuri halisi, kama vile halijoto katika Selsiasi.

Ninakadiriaje tofauti iliyopo kati ya mambo hayo mawili?

Divide the standard deviation by the mean and multiply by 100 to state it as a percentage. For a mean of 14 and a standard deviation of 3.16, the CV is 3.16 ÷ 14 × 100% ≈ 22.6%.

Kwa nini utumie CV badala ya ule utaratibu wa kawaida wa kuacha?

Kukengeuka kwa kiwango cha kawaida kunahusianishwa na vipimo na kiwango cha takwimu, kwa hiyo huwezi kulinganisha kwa haki usambaaji wa bei katika dola na kuenea kwa vipimo vya vipimo vya vipimo vya vipimo vya vipimo. Kugawanywa kwa makusudi huondoa vipimo, ukiruhusu kulinganisha upatano wa kadiri katika seti tofauti kabisa za data.

Je, utata wa mabadiliko ni sawa na kukengeuka kwa kiwango fulani?

Kukengeuka kwa kiwango fulani ni jina jingine linaloonyesha tofauti iliyopo kati ya aina mbili; maneno hayo mawili yanaweza kubadilishwa.

Je, nitumie sampuli au kiwango cha watu kuacha tabia?

Tumia njia hii ya tatu ikiwa namba zako zimetengwa na kikundi kikubwa, na uchaguzi wa watu wakati wote ni wa kikundi chote.
