Question 1 |

A working hypothesis is

a scientific theory. |

Question 2 |

Which one of the following is not a non-parametric test ?

t-test | |

Sign test | |

Chi-square test | |

Run test |

Question 3 |

"Male and female students perform equally well in a numerical aptitude test." This statement indicates a:

Statistical hypothesis | |

Research hypothesis | |

Null hypothesis | |

Directional hypothesis |

Question 4 |

In a research on the effect of child-rearing practices on stress –proneness of children in competing school projects, the hypothesis formulated is that ‘child rearing practices do influence stress- proneness’. At the data-analysis stage a null hypothesis is advanced to find out the tenability of research hypothesis. On the basis of the evidence available, the null hypothesis is rejected at 0.01 level of significance. What decision may be warranted in respect of the research hypothesis?

The research hypothesis will also be rejected. | |

The research hypothesis will be accepted. | |

Both the research hypothesis and the null hypothesis will be rejected. | |

No decision can be taken in respect of the research hypothesis. |

Question 5 |

Which of the following statements is true in the context of the testing of a hypothesis?

It is only the alternative hypothesis that can be tested. | |

It is only the null hypothesis that can be tested. | |

Both, the alternative and the null hypotheses can be tested. | |

Both, the alternative and the null hypotheses cannot be tested. |

Question 6 |

Formulation of hypothesis may NOT be required in:

Historical studies | |

Experimental studies | |

Normative studies |

Question 7 |

A null hypothesis is

when there is no difference between the variables | |

the same as research hypothesis | |

subjective in nature | |

when there is difference between the variables |

Question 8 |

To test null hypothesis, a researcher uses:

t test | |

ANOVA | |

X ^{2} | |

factorial analysis |

Question 9 |

We use Factorial Analysis:

To know the difference among the many variables |

Question 10 |

A hypothesis is a

law | |

canon | |

postulate | |

supposition |

Question 11 |

In the process of conducting research “Formulation of Hypothesis” is followed by

Statement of Objectives | |

Analysis of Data | |

Selection of Research Tools | |

Collection of Data |

Question 12 |

Identify the incorrect statement:

A hypothesis is made on the basis of limited evidence as a starting point for further investigations. | |

A hypothesis is a basis for reasoning without any assumption of its truth. | |

Hypothesis is a proposed explanation for a phenomenon. | |
