inferential statistics !

Inferential statistics is a branch of statistics that allows us to make conclusions or inferences about a population based on sample data. It involves using data from a smaller group (the sample) to draw conclusions about a larger group (the population). Here are some key concepts:

1. Population vs. Sample

Population: The entire group of individuals or instances that you want to draw conclusions about.
Sample: A subset of the population that is used to represent the whole.

2. Estimation

Point Estimate: A single value that serves as an estimate of a population parameter (e.g., sample mean as an estimate of the population mean).
Confidence Interval: A range of values, derived from the sample, that is believed to cover the true population parameter with a certain probability (e.g., 95% confidence interval).

3. Hypothesis Testing

Involves making an assumption (hypothesis) about a population parameter and then using sample data to test the validity of that assumption.
Null Hypothesis (H0): The hypothesis that there is no effect or no difference.
Alternative Hypothesis (H1): The hypothesis that there is an effect or a difference.
p-value: A measure that helps determine the significance of your results. A low p-value (typically < 0.05) indicates strong evidence against the null hypothesis.

4. Types of Tests

t-tests: Compare the means of two groups.
ANOVA: Compares means among three or more groups.
Chi-square tests: Assess relationships between categorical variables.
Regression analysis: Examines the relationship between variables and can be used for prediction.

5. Assumptions

Many inferential statistics methods rely on assumptions (e.g., normality, independence, homogeneity of variance). It’s important to check these assumptions before applying statistical tests.

6. Errors

Type I Error (α): Rejecting the null hypothesis when it is true (false positive).
Type II Error (β): Failing to reject the null hypothesis when it is false (false negative).

7. Applications

Inferential statistics is widely used in fields such as psychology, medicine, market research, and social sciences to make data-driven decisions.

Experimental Design !

Experimental design is a crucial aspect of conducting scientific research, allowing researchers to systematically investigate hypotheses while controlling variables to establish cause-and-effect relationships. Here are some key concepts and components to consider when designing an experiment:

1. Research Question and Hypothesis

Research Question: Clearly define what you want to investigate.
Hypothesis: Formulate a testable prediction based on your research question.

2. Variables

Independent Variable: The factor you manipulate in the experiment.
Dependent Variable: The factor you measure, which is affected by the independent variable.
Control Variables: Factors kept constant to ensure any changes in the dependent variable are due to the independent variable.

3. Control Group vs. Experimental Group

Control Group: Does not receive the experimental treatment, providing a baseline for comparison.
Experimental Group: Receives the treatment or intervention being tested.

4. Randomization

Randomly assign subjects to different groups to minimize bias and ensure that results are generalizable.

5. Sample Size

Determine an appropriate sample size to ensure your study has enough power to detect significant effects.

6. Blinding

Single-Blind: Participants do not know which group they are in, reducing bias in responses.
Double-Blind: Both participants and researchers are unaware of group assignments, further reducing bias.

7. Data Collection Methods

Choose appropriate methods for measuring your dependent variable (e.g., surveys, tests, physical measurements).

8. Statistical Analysis

Plan how you will analyze the data (e.g., t-tests, ANOVA) to determine if your results support your hypothesis.

9. Ethical Considerations

Ensure your experiment adheres to ethical guidelines, particularly when involving human or animal subjects.

10. Reproducibility and Transparency

Clearly document your methods and procedures so that others can replicate your study.

Example of an Experimental Design

Research Question: Does a new teaching method improve student test scores compared to traditional methods?

Hypothesis: Students taught with the new method will score higher on tests than those taught with the traditional method.
Independent Variable: Teaching method (new vs. traditional).
Dependent Variable: Student test scores.
Control Group: Students taught with the traditional method.
Experimental Group: Students taught with the new method.
Sample Size: 100 students randomly assigned to each group.
Blinding: Double-blind setup where neither students nor teachers know which method is being used until after the test.
Data Collection: Pre- and post-test scores to assess improvement.

Marketers Are Excited About GenAI, But Foggy On Business Impact !

Generative AI is being heavily used in marketing efforts, with 75% of marketers currently using it in their day-to-day work. However, 90% of CMOs admit they don’t fully understand how the technology will impact their business processes, according to a new global study from SAS and Coleman Parkes Research.

Marketers are leaders in Gen AI adoption, with 63% using the technology for tasks such as copywriting, editing, and content creation. The study found that 90% of marketers are investing in Gen AI in 2025, with the majority hoping to use the technology to save time and costs, improve risk management and compliance, or more efficiently process large data sets.

While these companies are embracing popular Gen AI functions like generating copy and interacting with customers, few are delving into its more sophisticated capabilities. Less than 20% of respondents have used the technology for audience targeting or building, mapping customer journeys, or price optimization.

It isn't surprising that marketers lead the way in Gen AI adoption, as it lends itself to experimentation and creativity — both hallmarks of the marketing profession," SAS chief marketing officer and executive vice president Jenn Chase said in a statement. "However, it is disappointing that a lack of understanding of Gen AI at the CMO and senior management level is holding organizations back from experiencing the full potential of this exciting new technology.

Time Series Forecasting: A Practical Guide to Exploratory Data Analysis !

Introduction

Time series analysis certainly represents one of the most widespread topics in the field of data science and machine learning: whether predicting financial events, energy consumption, product sales or stock market trends, this field has always been of great interest to businesses.

Obviously, the great increase in data availability, combined with the constant progress in machine learning models, has made this topic even more interesting today. Alongside traditional forecasting methods derived from statistics (e.g. regressive models, ARIMA models, exponential smoothing), techniques relating to machine learning (e.g. tree-based models) and deep learning (e.g. LSTM Networks, CNNs, Transformer-based Models) have emerged for some time now.

Despite the huge differences between these techniques, there is a preliminary step that must be done, no matter what the model is: Exploratory Data Analysis.

In statistics, Exploratory Data Analysis (EDA) is a discipline consisting in analyzing and visualizing data in order to summarize their main characteristics and gain relevant information from them. This is of considerable importance in the data science field because it allows to lay the foundations to another important step: feature engineering. That is, the practice that consists on creating, transforming and extracting features from the dataset so that the model can work to the best of its possibilities.

The objective of this article is therefore to define a clear exploratory data analysis template, focused on time series, which can summarize and highlight the most important characteristics of the dataset. To do this, we will use some common Python libraries such as Pandas, Seaborn and Statsmodel.

Data

Let’s first define the dataset: for the purposes of this article, we will take Kaggle’s Hourly Energy Consumption data. This dataset relates to PJM Hourly Energy Consumption data, a regional transmission organization in the United States, that serves electricity to Delaware, Illinois, Indiana, Kentucky, Maryland, Michigan, New Jersey, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia, and the District of Columbia.

The hourly power consumption data comes from PJM’s website and are in megawatts (MW).

Exploratory Data Analysis

Let’s now define which are the most significant analyses to be performed when dealing with time series.

For sure, one of the most important thing is to plot the data: graphs can highlight many features, such as patterns, unusual observations, changes over time, and relationships between variables. As already said, the insight that emerge from these plots must then be taken into consideration, as much as possible, into the forecasting model. Moreover, some mathematical tools such as descriptive statistics and time series decomposition, will also be very useful.

Said that, the EDA I’m proposing in this article consists on six steps: Descriptive Statistics, Time Plot, Seasonal Plots, Box Plots, Time Series Decomposition, Lag Analysis.
1. Descriptive Statistics

Descriptive statistic is a summary statistic that quantitatively describes or summarizes features from a collection of structured data.

Some metrics that are commonly used to describe a dataset are: measures of central tendency (e.g. mean, median), measures of dispersion (e.g. range, standard deviation), and measure of position (e.g. percentiles, quartile). All of them can be summarized by the so called five number summary, which include: minimum, first quartile (Q1), median or second quartile (Q2), third quartile (Q3) and maximum of a distribution.

The naturalist perspective of the human being: A critique from the phenomenological perspective !

The remarkable advances in the fields of science and technology during the last few decades are strongly influencing the way we human beings perceive ourselves. A more integrated, humanist perspective is giving way to a mechanist, naturalist perspective.

With the tendency to reduce everything that exists to data or information in the present digital age, the human being too is considered by some as nothing more than a complex biological machine, having reached this stage through merely accidental evolutionary pathways.

A related viewpoint is that the human mind is seen as a highly sophisticated computer whose programming software will be fully known in the near future through research in the cognitive sciences. Though, on the one hand, many intellectuals, including scientists and philosophers, do not agree with the naturalist perspective, on the other, there are a sizable number who are convinced about the truth of this perspective.

Moreover, this perspective of the human being is also being widely diffused through the communication media as it appeals to the public imagination and endorses the unprecedented progress in science and technology achieved by humanity. As a result, the naturalist perspective of the human being is increasingly gaining prominence.
