Hypothesis Types
Null Hypothesis
Alternative Hypothesis
• If we are to compare
method A with method B
about its superiority and
if we proceed on the
assumption that both
methods are equally
good, then this
assumption is termed as
the null hypothesis.
• अगर हम विवि A की विवि B
क
े साथ इसकी श्रेष्ठता क
े बारे में
तुलना करते हैं और यवि हम
इस िारणा पर आगे बढ़ते हैं वक
िोनोों विवियााँ समान रूप से
अच्छी हैं, तो इस िारणा को
शून्य पररकल्पना कहा जाता
है।
• As against this, we may think that the method A is superior
or the method B is inferior, we are then stating what is
termed as alternative hypothesis.
• इसक
े विरूद्ध, हम सोच सकते हैं वक विवि A श्रेष्ठ है या विवि B अिर है,
हम विर बताते हैं वक िैकल्पिक पररकिना को क्या कहा जाता है।
• If our sample results do not
support this null hypothesis, we
should conclude that something
else is true.
• What we conclude rejecting the
null hypothesis is known as
alternative hypothesis.
• In other words, the set of
alternatives to the null
hypothesis is referred to as the
alternative hypothesis.
• If we accept H0 , then we are
rejecting Ha
and
• if we reject H0 , then we are
accepting Ha
• यवि हमारे नमूना पररणाम इस शून्य
पररकिना का समर्थन नह ीं करते हैं, तो हमें
यह वनष्कर्थ वनकालना चावहए वक क
ु छ और
सच है।
• हम जो शून्य पररकिना को खाररज करते
हैं, उसे िैकल्पिक पररकिना क
े रूप में
जाना जाता है।
• िू सरे शब्ोीं में, शून्य पररकिना क
े विकि
क
े विकि को िैकल्पिक पररकिना क
े
रूप में जाना जाता है।
• यवि हम H0 को स्व कार करते हैं, तो हम हा
को अस्व कार कर रहे हैं तर्ा यवि हम H0
को अस्व कार करते हैं, तो हम हा को
स्व कार कर रहे हैं
The null hypothesis and the alternative
hypothesis are chosen before the
sample is drawn.
(a) Alternative hypothesis is usually the
one which one wishes to prove and
the null hypothesis is the one which
one wishes to disprove.
Thus, a null hypothesis represents the
hypothesis we are trying to reject, and
alternative hypothesis represents all
other possibilities.
a) िैकल्पिक पररकिना आमतौर पर
िह होत है वजसे कोई सावबत करना
चाहता है और अशक्त पररकिना
िह है वजसे कोई अस्व कार करना
चाहता है।
इस प्रकार, एक शून्य पररकिना उस
पररकिना का प्रवतवनवित्व करत है
वजसे हम अस्व कार करने का प्रयास कर
रहे हैं, और िैकल्पिक पररकिना अन्य
सभ सींभािनाओीं का प्रवतवनवित्व करत
है।
(b)Null hypothesis should always be specific hypothesis i.e., it
should not state about or approximately a certain value.
(b) अशक्त पररकिना सिैि विवशष्ट पररकिना होन चावहए अर्ाथत,
यह वकस वनवित मान क
े बारे में या उसक
े बारे में नह ीं बताना चावहए।
Generally, in hypothesis testing we proceed on the basis of null hypothesis,
keeping the alternative hypothesis in view.
आमतौर पर, पररकिना पर क्षण में हम िैकल्पिक पररकिना को ध्यान में रखते हुए
अशक्त पररकिना क
े आिार पर आगे बढ़ते हैं।
