a) Var(X) - Var(Y)
b) Var(X) + Var(Y)
c) Var(X - Y)
d) Var(X) `\times` Var(Y)
The correct answer is 'a'.
If X and Y are independent variables then Var (X - Y) = Var(X) - Var(Y)
______________________________
a) Extreme values
b) Minimum values
c) Maximum values
d) Mid-range values
The correct answer is 'a'.
Range measures the dispersion around the extreme values.
______________________________
a) Scatter Variable
b) Independent Variable
c) Dependent Variable
d) Correlation Variable
The correct answer is 'b'.
The variable plotted on the horizontal or X-axis in a scatter diagram is called the independent variable.
______________________________
a) X and Y
b) X and `\hatY`
c) X and `\hatY`
d) `\hatY` and X
The correct answer is 'a'.
In a scatter diagram, we plot the variables X and Y.
______________________________
a) Independent
b) Mutually Exclusive
c) Dependent
d) Equally Likely
The correct answer is 'a'.
If `P(A \cap B) = P(A|B) \times P(B)`, then A and B are statistically independent events.
______________________________
a) The number of observations in each
class
b) The difference between consecutive lower
class limits
c) Always contains at least 5
observations
d) Usually a multiple of the lower limit
of the first class.
The correct answer is 'a'.
The class frequency refers to the number of observations or occurrences within a particular class or category in a data set.
______________________________
a) Find the difference between
consecutive lower class limits
b) Find the difference between consecutive lower limits
c) Count the number of observations in
the class
d) Divide the class frequency by the
total number of observations
The correct answer is 'd'.
To convert a frequency distribution to a relative frequency distribution, you divide the class frequency by the total number of observations.
______________________________
a) Individuals
b) Isolated items
c) Aggregates of facts
d) Qualitative data
The correct answer is 'c'.
In statistics, we deal with aggregates of facts.
______________________________
a) A rectangular
b) A triangle
c) A square
d) A circle
The correct answer is 'd'.
A pie chart is a circular statistical graphic that is divided into slices to represent different categories or proportions of a whole. Each slice of the pie chart represents a specific category or data point, and the size of the slice corresponds to the proportion or percentage it represents.
______________________________
a) 1
b) 2
c) 3
d) 4
The correct answer is 'c'.
If the distribution is symmetrical and `Q_1` (the first quartile) is 2 and `Q_3` (the third quartile) is 4, then the value of the median (also known as the second quartile,` Q_2)` would be the average of `Q_1` and `Q_3`.
Therefore, the value of the median would be:
(`Q_1` + `Q_3`) / 2 = (2 + 4) / 2 = 6 / 2 = 3.
