The mean, median and mode calculator returns the three measures of central tendency for a data set — the mean (arithmetic average), the median (middle value) and the mode (most frequent value) — plus the count, sum, range and the full five-number summary (minimum, first quartile, median, third quartile and maximum). Enter your numbers separated by commas or spaces.
The mean is the sum of all the values divided by how many there are. The median is found by sorting the data and taking the middle value, or the average of the two middle values when the count is even. The mode is whichever value appears most often; when every value is unique there is no mode, and when several values tie for the highest frequency the set is multimodal and all of them are shown.
Worked example: for 4, 8, 15, 16, 15, 23, 42 the sum is 123 across 7 values, so the mean is 123 ÷ 7 ≈ 17.57. Sorting gives 4, 8, 15, 15, 16, 23, 42, so the median (the fourth of seven values) is 15, and 15 is also the mode because it occurs twice while every other value occurs once. A frequency table and distribution chart break the data down value by value, which is useful for grades, survey scores, prices or any list where you need the typical value at a glance.
Mafunso ofunsidwa nthawi zambiri
Kodi pali njira ina?
A data set ali ndi palibe mode pamene zonse mfundo zikuchitika moyenera nthawi imodzi. Ngati awiri kapena zambiri mfundo kugawana kwambiri machitidwe, set ndi bimodal kapena multimodal ndi aliyense wa iwo mfundo ndi mode.
Kodi ndiyenera kudziwitsa za m'mimba mwake kapena m'mimba mwake?
Kugwiritsa ntchito mwamsanga kwa kusamvana kwa data kapena pamene outliers ndipo, chifukwa sichidzagwidwa ku malingana kwambiri. M'midzi ndi yabwino kwa pafupifupi symmetric deta ndi palibe outliers kwambiri.
Kodi pali kusiyana kotani pakati pa mfundo yoyamba ndi mfundo yoyamba?
M'mawu ena, mfundo yapakati imawonjezera zonse zomwe zilipo ndipo imagawanitsa ndi kuchuluka, kotero kuti zonse zomwe zilipo zimatenga gawo limodzi la mfundo yapakati, ndipo mfundo imodzi yosagwirizana ndi mfundo ina imatha kusinthidwa kwambiri. M'mawu ena, mfundo yapakati ndi mfundo yapakati yomwe imapezeka pamene deta ikusankhidwa, kotero kuti imasiya kuganizira kuti deta yosagwirizana ndi deta ina ili bwanji.
Kodi ndi mmene median anapeza pamene pali ngakhale ochepa chabe matanthauzo?
With an even count there is no single middle value, so the median is the average of the two central values. For 2, 4, 6, 8 the two middle numbers are 4 and 6, giving a median of 5.
Kodi akhoza kusonkhanitsa deta kukhala ndi modes ambiri kuposa mmodzi?
Ngati maganizo awiri kapena ambiri kugwirizana kwa apamwamba kwambiri nthawi set ndi bimodal kapena multimodal, ndipo izi mwamsanga, median ndi mode calculator limati zonse maganizo kuti amafika kuti pamwamba nthawi nthawi kuposa kuika mmodzi yekha.
Kodi m'madera anganene chiyani?
The range is the difference between the largest and smallest values, a quick but crude measure of spread. For 4, 8, 15, 16, 15, 23, 42 it is 42 − 4 = 38. Because it uses only the two extremes it is very sensitive to outliers.
Kodi ndi quartiles anasonyeza pansi pa zotsatira?
Kuyambira ndi yachitatu quartiles ndi 25th ndi 75th percentiles, choncho pakati pa gawo limodzi la deta yanu limakhala pakati pa iwo. Kuphatikizana ndi minimum, median ndi maximum iwo amapanga mnda wa ma digito asanu amene amafotokoza mtundu wa kugawa.
