Question 1

Which is the type of correlation on the basis of number of variables?
A)Positive correlation
B)Multiple correlation
C)Linear Correlation
D)Non-linear Correlation

Accepted Answer

Multiple correlation is a type of correlation that involves more than two variables.

Question 2

Which characteristics come under Karl Pearson's Coefficient of Correlation?
A)Does not tell anything about cause-and-effect relationship
B)Independent of change of origin and scale
C)Varies between -1 and +1
D)All of the above

Accepted Answer

Karl Pearson's Coefficient of Correlation is designed to measure the strength and direction of the linear relationship between two variables, without implying causation (A), is calculated in a way that it remains unaffected by changes in the location and scale of the data (B), and by definition, it ranges from -1 to +1, indicating perfect negative correlation at -1, no correlation at 0, and perfect positive correlation at +1 (C).

Question 3

If one knows that the yield and rainfall are closely related then one want to know the amount of rain required to achieve a certain production. For this purpose we use analysis
A)Regression Analysi
B)Coefficient of Correlation
C)Scatter Plots/Diagram
D)None of these

Accepted Answer

Regression Analysis is used to understand the relationship between variables and can be used to predict the amount of rain required to achieve a certain level of production based on the relationship between yield and rainfall.

Question 4

When two attributes are present or absent together in the data and actual frequency is more than the expected frequency is called
A)Positive Association
B)Negative Association
C)Independent Association
D)None of these

Accepted Answer

Positive Association occurs when two attributes are present or absent together more frequently than expected by chance, indicating a relationship between the presence of one attribute and the presence of another.

Question 5

Which is not type of test of significance for small sample ?
A)t- test
B)z-test
C)F-test
D)Q-test

Accepted Answer

Q-test is not a type of test of significance for small sample.

Question 6

Which test is the part of the parametric test?
A)Sign Test
B)Run Test for Randomness
C)Kruskal-Willis Test
D)z-test

Accepted Answer

The z-test is a parametric test because it assumes that the data follows a normal distribution and requires knowledge of the population variance.

Question 7

Which analysis comes under inferential analysis?
A)Univariate Analysi
B)Bivariate Analysis
C)Multivariate Analysis
D)Hypothesis Testing

Accepted Answer

Hypothesis testing is a part of inferential analysis as it involves making inferences or predictions about a population based on a sample of data.

Question 8

The procedure of classifying the answers to a question into meaningful categories is called
A)Coding
B)Classification
C)Editing
D)Tabulation

Accepted Answer

Coding involves organizing or transforming the answers to questions into categories or codes, which can then be easily analyzed.

Question 9

Which of the following constitute the essential elements of coding ?
A)Mutually exclusive
B)Single Dimension
C)Code Sheet
D)all of these

Accepted Answer

The essential elements of coding include being mutually exclusive, having a single dimension, and utilizing a code sheet. These elements ensure that each piece of data is categorized uniquely, the coding system focuses on one characteristic at a time, and there is a structured document (code sheet) for reference, respectively.

Question 10

Which among the following is type of frequency?
A)Relative frequency
B)Percentage frequency
C)Cumulative frequency
D)All of the above

Accepted Answer

All of the options listed, Relative frequency, Percentage frequency, and Cumulative frequency, are types of frequencies used in statistics to describe different ways of summarizing data.

Question 11

A bar chart or graph showing the frequency of occurrence of each value of the variable being analysed is called
A)Bar Chart
B)Histogram
C)Candle stick
D)None of these

Accepted Answer

A histogram is specifically designed to show the frequency of occurrence of each value (or range of values) of a variable, making it the correct choice for this description.

Question 12

A chart is a style of bar-chart used primary to describe price movements of a security, derivative, or currency over time is called
A)Leaf and stem
B)Histogram
C)Candle Stick
D)Bar chart

Accepted Answer

Candle Stick charts are specifically used to describe price movements of securities, derivatives, or currencies over time, showcasing open, high, low, and close values within specific periods.

Question 13

A group of observations is the quotient obtained by dividing the sum of all the observations by their number, is called
A)Mean
B)Median
C)Mode
D)None of these

Accepted Answer

The mean of a group of observations is calculated by dividing the sum of all the observations by their number, which is the definition provided.

Question 14

Which analysis is the simultaneous analysis of two variables?
A)Univariate Analysis
B)Bivariate Analysis
C)Multivariate Analysis
D)None of these

Accepted Answer

Bivariate analysis is the simultaneous analysis of two variables.

Question 15

Which Statistical tool comes under Bivariate Analysis ?
A)Linear Regression Analysis
B)Association of Attributes
C)Two-way ANOVA
D)All of the above

Accepted Answer

All of the options listed, Linear Regression Analysis, Association of Attributes, and Two-way ANOVA, are tools used in bivariate analysis to examine the relationship between two variables.

Question 16

The assumption of normal distribution for the variable under consideration or some assumption for a parametric test is not valid or is doubtful then we use
A)Parametric Test
B)Non-Parametric Test
C)Both Parametric Test and Non-Parametric Test
D)All of the above

Accepted Answer

Non-parametric tests do not assume a specific distribution for the data, making them suitable when the assumption of normality is not valid or is in doubt.

Question 17

What is abbreviation of ANOVA?
A)Analysis of variance
B)Analysis of variation
C)Analysis of variant
D)None of these

Accepted Answer

ANOVA stands for Analysis of Variance, a statistical method used to compare means of three or more samples.
