Section-A :
Q1. Multiple Choice Questions :
Choose one most correct answer from the provided choices. Write your choice on the right hand side column only. Illegibly written answers will not be considered. Each Question carries two marks. (2×10 marks)

i) Why is a control necessary in a well planned experiment?
a) To show what would normally happen and compare it with what happens when you change the independent variable.
b) To keep the experiment from becoming chaotic.
c) So that the experiment can be contained.
d) For graphing purposes only

ii) Consider the following data : 14; 16; 16; • 22; 25; 38; 38; 38; 38; 2000
Which of the measures of central tendency would be the least useful?
a) mean
b) mode
c) median

iii) As the degrees of freedom increase (and especially when the degrees of freedom are more than 90), the graph of the chi-square distribution looks more and more ______________.
a) symmetrical
b) skewed right
c) skewed left
d) asymmetrical

iv) The Goodness-of-Fit hypothesis test is typically a ______________.
a) two-tailed test
b) wagging-tailed test
c) left-tailed test
d) right-tailed test

v) Determine the sampling technique :
A medical researcher does a random survey of 100 female doctors and 100 male doctors.
a) stratified
b) systematic
c) simple random
d) cluster

vi) Following is not the example of tests.
a) Chi test b) t-test c) pie test d) F-test
vii) Following is not the part of basic principles of experimental designs
a) Replication b) Randomization c) Local Control d) Reduction

viii) Following is the type of informal experimental designs.
a) Before-and after with control design
b) b) Completely randomized Design
c) Latin square Design
d) Factorial Designs

ix) For data that is normally distributed, is it possible for the standard deviation to be larger than the mean?
a) No.
b) Yes.
c) There is not enough information to determine.

x) What is the difference between the independent and dependent variables in an experiment?
A. The independent variable is quantitative and the dependent variable is not.
B. The independent variable is what is changed and the dependent variable is what is measured.

C. The independent variable has disowned his parents and the dependent variable still relies on them for food, shelter, and gas money.
D. The independent variable is graphed on the y-axis and the dependent is graphed on the x-axis.

Q2. Fill in the Blanks : (2 x 10 marks)
i) ————— refers to a design that has more than one independent variable.
ii) ——————————- is an external variable that affects the internal variable and intertwines with other extraneous variables such that it is difficult to determine unique effects of each.

iii) ——————————- is the non-manipulated variable in factorial design.
iv) ——————- is an arbitrary value, designated as the significance level.
v) ——————– is the measure of the flat-toppedness of a distribution curve

vi) —————— factorial designs consider the effect of varying two factors on the dependent variable.
vii) ——————— technique is used design or plan the experiment in such a way that thew variations caused by extraneous factors can all be combined under the general heading of “chance”.

viii) ———————– measures seperstely the relationship between two variables in such a way that the effects of other related variables are eliminated.
ix) ————————- defines the limits within which the parameters of the population are expected to lie with a specified degree of confidence.

x) When there really is a difference (association, correlation) overall, but random sampling caused your data to not show a statistically significant difference, the errors responsible for this are called ________________
