Accepted Answer

Statistics (plural) refers to numerical facts and figures such as sales, costs, profits, etc.

Question 3

Define data.

Accepted Answer

Question 4

What is a population?

Accepted Answer

Population is the entire group or universe of units under study.

Question 5

What is a sample?

Accepted Answer

A sample is a part (subset) selected from the population for study.

Question 6

State one use of business statistics.

Accepted Answer

One use is forecasting sales/demand or decision making (any one).

Question 7

Write any three uses of statistics in business.

Accepted Answer

Uses of statistics in business include:

1) Planning and policy making (targets, strategies).
2) Forecasting demand, sales and costs.
3) Quality control and performance comparison.

(Any three uses can be written.)

Question 8

Write any three limitations of statistics.

Accepted Answer

Limitations of statistics include:

1) It deals mainly with quantitative data; qualitative aspects need conversion.
2) Results depend on quality of data and method used.
3) Statistics can be misused to mislead if presented wrongly.

(Any three limitations can be written.)

Question 9

Differentiate between population and sample (any three points).

Accepted Answer

Population and sample differ as follows:

| Point | Population | Sample |
|---|---|---|
| Meaning | entire group | subset of population |
| Cost/time | high | lower |
| Use | census studies | surveys/estimation |

(Any three points can be written.)

Question 10

Differentiate between qualitative and quantitative data (any three points).

Accepted Answer

Qualitative and quantitative data differ as follows:

| Point | Qualitative (categorical) | Quantitative (numerical) |
|---|---|---|
| Nature | categories/attributes | numbers/measurements |
| Example | brand, gender | income, sales |
| Operations | counting, percentages | arithmetic, averages |

(Any three points can be written.)

Question 11

Explain any three characteristics of statistics (as data).

Accepted Answer

Characteristics of statistics include:

1) Statistics are aggregates of facts (not a single observation).
2) They are expressed numerically and collected for a definite purpose.
3) They are comparable and related to time/place; affected by multiple causes.

(Any three characteristics can be written.)

Question 12

Explain any three scales of measurement with examples.

Accepted Answer

Scales of measurement include:

1) Nominal: labels only (e.g., product category).
2) Ordinal: ranking/order (e.g., satisfaction low/medium/high).
3) Ratio: true zero and equal intervals (e.g., sales, income).

(Any three scales can be written.)

Question 13

Explain meaning and scope of business statistics with suitable examples.

Accepted Answer

Business statistics is the application of statistical methods to business problems. It helps convert raw data into useful information for planning, decision making, forecasting and control.

**Meaning:** Statistics (singular) is the science of collecting, organizing, presenting, analyzing and interpreting data. In business, it is used to study sales, costs, profits, customer preferences, production defects and market trends.

**Scope of business statistics** includes:

- collection of data (primary/secondary, sampling)
- classification, tabulation and presentation (tables/graphs)
- measures of central tendency and dispersion
- correlation and regression
- index numbers and time series
- basic probability and inference

For example, a company can use statistics to analyze monthly sales data, calculate average sales, measure variation, and forecast demand for the next quarter.

Thus, business statistics provides a scientific base for managerial decisions in uncertain situations.

Question 14

Differentiate types of data and scales of measurement using tables.

Accepted Answer

In business statistics, understanding data types and measurement scales is important because the choice of statistical method depends on them.

**Types of data:**

| Type | Meaning | Example |
|---|---|---|
| Qualitative | categories/attributes | brand, gender, region |
| Quantitative | numerical values | income, sales, age |

Quantitative data can be discrete (countable: number of defects) or continuous (measurable: time, weight).

**Scales of measurement:**

| Scale | Key feature | Example |
|---|---|---|
| Nominal | labels only | product category |
| Ordinal | ranking | satisfaction low/medium/high |
| Interval | equal intervals, no true zero | temperature (°C) |
| Ratio | equal intervals + true zero | sales, income |

Thus, tables help clearly differentiate data and measurement levels, making it easier to select correct statistical tools for analysis.

Question 15

Explain uses of statistics in business and also mention limitations. Use a table and conclude.

Accepted Answer

Statistics plays a major role in business because it supports evidence-based decisions. At the same time, it has certain limitations, so it must be used carefully.

**Uses of statistics in business:**

| Area | How statistics helps |
|---|---|
| Planning | setting targets using trends |
| Forecasting | predicting demand, sales, costs |
| Decision making | comparing alternatives based on data |
| Quality control | monitoring defects and variation |
| Market research | analyzing surveys and customer preferences |

**Limitations:**

1) Statistics mainly deals with quantitative facts; qualitative issues must be converted into numbers.
2) Conclusions depend on data quality, sampling and correct methods.
3) Results are not always exact; many decisions are probabilistic.
4) Statistics can be misused to mislead by wrong graphs or biased averages.

Therefore, statistics should be used with proper data collection, correct methods and honest interpretation. When used correctly, it becomes a powerful tool for business success.
