Study Notes
Business Statistics: Introduction and Data Collection
- Business statistics is a branch of mathematics transforming numbers into useful information for decision-makers.
- Statistics is used in business memos, research, technical reports, journals, newspapers, and magazines.
- Statistical methods help understand the ubiquitous use of numbers, reduce uncertainty in decision-making, and present data properly.
- Decision-makers use statistics to present business data (e.g., tables, figures), draw conclusions from subsets of data (e.g., student weight in a class), make forecasts about a business activity (e.g., oil prices), and improve business processes.
- Statistics are divided into two main categories: Descriptive and Inferential.
Types of Statistics
- Descriptive Statistics: Collect, summarize, and describe data (e.g., mean, median). Tables and graphs are used to present data visually.
- Inferential Statistics: Draw conclusions and make decisions concerning a population based only on sample data. For example, estimate the population mean weight based on a sample mean weight.
Data
- Data are collections of observations (measurements, genders, survey responses).
- Data is categorized into Numerical (discrete and continuous), and Categorical (attribute). Numerical data represents measured numbers or counts, while Categorical data is in names or labels.
Data Types
- Numerical (Quantitative) Data: Represents counts or measurements
- Discrete: Finite or countable number of values (e.g. number of eggs laid by a hen)
- Continuous: Infinite number of values within a given range (e.g., the amount of milk produced by a cow)
- Categorical (Qualitative) Data: Names or labels representing categories. (e.g. Gender (male/female), shirt sizes)
Levels of Measurement
- Nominal: Consists of names, labels, or categories only. Cannot be ordered (e.g., survey responses yes, no, undecided)
- Ordinal: Data can be arranged in some order, but differences between values are meaningless or undetermined (e.g., course grades A, B, C, D, F)
- Interval: Differences between data values are meaningful, but there is no natural starting point (e.g., years 1000, 2000, 1776)
- Ratio: Similar to interval but with a meaningful, natural zero starting point (e.g., prices of college textbooks)
Sampling
- Population: The complete collection of individuals (e.g., scores, people, measurements) to be studied.
- Census: Collection of data from every member of the population.
- Sample: A subcollection of members selected from the population. Collecting sample data properly is critical; otherwise, it may be useless. Proper collection methods such as simple random sampling are vital for statistical analysis.
- Sampling Methods: Random, systematic, convenience, stratified, cluster, and multistage.
Personal Computer Programs Used for Statistics
- Minitab: A statistical package designed to perform statistical analysis as accurately as possible.
- Microsoft Excel: A multi-functional data analysis tool that can perform various tasks, including storing data in worksheets.
Key Points
- Data collection, analysis, and interpretation methods depend on statistics.
- Choosing the right sampling methods is vital when collecting and interpreting data.
- Using appropriate software such as Minitab and Excel helps organize and analyze collected data.
