স্লাইড ১

The Story of Research

স্লাইড ২

Before anything else

স্লাইড ৩

Where this goes

The whole map is on the table in the first ten minutes. Phase I gives the vocabulary. Phase II teaches you to read and design. Phase III lets you analyze. Phase IV is literacy. Nothing in Phase III arrives before the language for it exists.

স্লাইড ৪

The exit competency

This is the public promise. By Session 30 you can be handed an unfamiliar medical paper, in a field that is not yours, and say what it asked, whether the design could answer it, what the numbers mean, where it is vulnerable, and whether you believe it.

স্লাইড ৫

Notice What Is Missing

If you leave able to calculate something, the wrong class was taught. Session 1 is about how a doctor comes to believe something, how a paper is built, and where statistics actually enters. The algebra waits.

স্লাইড ৬

Act I · Why Does Research Exist at All?

স্লাইড ৭

A question for a doctor with ten years behind him

স্লাইড ৮

Three ways of believing

Authority fails when it is only repeating a teacher. Experience fails because you never meet the patient you did not treat. Evidence is the third kind of knowing, done deliberately enough to be checked. Research is not a different kind of knowing. It is that third one.

স্লাইড ৯

Act II · The Anatomy of a Paper

স্লাইড ১০

The paper we live inside

The first paper is a real trial, not a toy example. COBRA-BPS is taken apart the same afternoon the course begins, so every later session can point back at a study the room already knows.

স্লাইড ১১

Every paper has the same skeleton

Title, abstract, introduction, methods, results, discussion, references. Once the skeleton is named, reading stops being a hunt through prose and becomes a walk through rooms that always appear in the same order.

স্লাইড ১২

The title has already told you the design

স্লাইড ১৩

Reading an abstract in five moves

স্লাইড ১৪

The same five moves have a name: PICO

স্লাইড ১৫

Where the numbers actually live

স্লাইড ১৬

What they found

স্লাইড ১৭

One sentence, in slow motion

স্লাইড ১৮

Why the interval matters more than the verdict

স্লাইড ১৯

The same result, in a different currency

স্লাইড ২০

Is 5.2 mm Hg worth it?

স্লাইড ২১

Five questions, every paper, forever

What was asked, of whom, how, what was found, and whether you believe it. These five survive the whole program. Later sessions add tools. They do not replace this list.

স্লাইড ২২

Act III · So Where Does Statistics Actually Enter?

স্লাইড ২৩

It was there the whole time

স্লাইড ২৪

The one distinction this session exists to teach

Description is a statement about the people you measured. Inference is a statement about the people you did not. Every number in a paper belongs in one of those two boxes. Session 1 ends when that sort can be done out loud.

স্লাইড ২৫

The arrow that points backwards

You measured a sample. You want a sentence about a population. The arrow points the wrong way for comfort, which is why statistics exists at all. The next session names who the population is and what one row of the data actually is.

স্লাইড ২৬

Why we can never simply be certain

স্লাইড ২৭

Two ways to be wrong, in a table you already know

স্লাইড ২৮

The mean is the same. The patients are not.

স্লাইড ২৯

What statistics cannot fix

স্লাইড ৩০

Not all evidence weighs the same

স্লাইড ৩১

Act IV · Your Turn

স্লাইড ৩২

Where research questions actually come from

স্লাইড ৩৩

Now write one of your own

স্লাইড ৩৪

What a clinical research career abroad actually asks for

স্লাইড ৩৫

Before the next session

স্লাইড ৩৬
