What is Quantitative Data: Definition, Types, & Analysis

This article will explore what quantitative data is, outlining its meaning, types, and examples, while briefly viewing its collection and analysis methods.

What Does Quantitative Data Mean?

Quantitative data refers to information that is measurable and expressed numerically. It is crucial for statistical analysis, answering questions like “how many,” “how often,” or “how much,” providing insights into quantities and frequencies.

What are Some Quantitative Data Examples?

Quantitative data can be found in various aspects of daily life. Examples of quantitative data include measurements like weight in kilograms or pounds, age in years, or distance traveled in miles. 

In the financial world, examples of quantitative data include daily trading volumes of stocks, a company’s annual revenue growth percentage, interest rates, market capitalization, and more. 

Quantitative Data vs Qualitative Data

Qualitative data and quantitative data are fundamentally different. It is important to understand their characteristics to make the appropriate choice for effective analysis.

 The difference between quantitative and qualitative data.

How is Qualitative Data Different from Quantitative Data?

So, what exactly is the difference between quantitative and qualitative data? Unlike quantitative data, which is numerical and measurable, qualitative data is descriptive information expressed through words, visuals, or other non-numerical formats

Quantitative data also focuses on understanding the “why” behind phenomena, describing the attributes, characteristics, or themes. It is often used to group information according to themes, patterns, or categories derived from observations, interviews, or text analysis.

Examples of qualitative data in the finance industry include customer reviews of financial products, market sentiment analysis derived from news articles or social media posts, expert opinions on market trends, and descriptions of company culture or management style. 

How to Choose Between Quantitative and Qualitative Data?

Choosing between quantitative and qualitative data depends on the research objectives. 

As we’ve mentioned, quantitative data is ideal when you need to measure and analyze numerical information to answer questions like “how many,” “how much,” or “how often.” This means it’s best suited for identifying trends and making comparisons in statistical analysis. For example, if you want to determine the average return on investment for a specific stock over the past year, quantitative data is necessary.

On the other hand, qualitative data is better suited for exploring subjective experiences, opinions, and motivations, as it focuses on the questions “why” and “how”. For example, to understand why investors prefer certain financial products or how they feel about market conditions, qualitative data gathered from interviews, surveys, or sentiment analysis can provide a deeper context.

In many cases, combining both types—quantitative for measurable trends and qualitative for underlying reasons—can yield the most comprehensive insights. As for now, we will continue to focus on quantitative data for this article.

What are the Different Types of Quantitative Data?

Quantitative data can be further classified into two main types: discrete and continuous. 

Discrete data can only take distinct, countable values. This means discrete data are typically whole numbers and cannot be meaningfully divided into fractions. Examples include bond ratings, the total number of trades executed in a day, or a company’s current amount of outstanding shares. 

Conversely, continuous data can take any value within a given range while fluctuating over time. Examples include stock prices, interest rates, or currency exchange rates. Their values can be measured with greater precision and can include decimals or fractions.

How is Quantitative Data Collected?

Quantitative data is usually gathered using structured methods to ensure accuracy for analysis. Common quantitative data collection methods include:

  • Surveys and Questionnaires: These are often conducted using closed-ended questions to collect numerical data from large groups.
  • Interviews: While traditionally qualitative, this method can also collect quantitative data through structured questions with fixed, quantifiable responses.
  • Observations: This involves the systematic recording of measurable behaviors or events through structured observations.
  • Reviewing Existing Datasets: For a more efficient approach, some analysts may leverage public datasets from government agencies or research institutions. There are also industry-specific datasets like TEJ that offer access to vast, high-quality data, allowing for accurate analysis and actionable insights within your chosen sector.

What are the Common Quantitative Data Analysis Methods?

Two primary approaches to quantitative data analysis are descriptive and inferential statistics:

  • Descriptive Statistics Analysis: This method summarizes and organizes data to reveal its basic characteristics. It includes measures like mean, median, mode, range, and standard deviation, offering a glimpse of trends and patterns in the dataset.
  • Inferential Statistics Analysis: Going beyond description, this approach draws conclusions and makes predictions about a population based on sample data. It involves hypothesis testing, confidence intervals, and regression analysis to assess probabilities and relationships.

Choosing between these methods depends on the research goals; descriptive statistics are used for summarizing data, while inferential statistics are used for making generalizations.

Why is Quantitative Data Used in Finance?

Quantitative data is fundamental to modern finance, particularly for quantitative traders (quants). Quants rely heavily on numerical data and statistical models to identify trading opportunities and manage risk. 

By analyzing vast amounts of historical and real-time data, they can uncover patterns, correlations, and irregularities that might not be apparent through traditional qualitative analysis. This data-driven approach allows them to develop automated trading strategies, optimize portfolios, and make informed investment decisions.

Quantitative data allows investors to develop automated trading strategies to spot opportunities and manage risks with efficiency.

As examples, here are two use cases demonstrating the application of quantitative data in finance:

Algorithmic Trading with Pattern-Based Strategies 

Quants develop algorithms that automatically execute trades based on predefined criteria derived from quantitative data. For instance, an algorithm might be programmed to buy a stock when its price drops below a certain moving average and sell it when it rises above another threshold, all determined by historical price and volume data.

Risk Management with Volatility Models 

Risk reduction is another critical application. For example, risk-parity portfolios adjust asset allocation based on market volatility. When volatility rises, the portfolio shifts to safer assets like cash; when volatility falls, it reallocates to higher-risk assets for greater returns.

With quantitative data, financial professionals can make more objective and data-backed decisions.
