The scientific method involves making observations, asking questions, forming hypotheses to answer those questions, designing experiments to test the hypotheses, collecting and analyzing data, and drawing conclusions. It is a systematic process used by scientists to explore the natural world and discover answers to questions. The steps of the scientific method are making observations, asking questions, gathering information, forming a hypothesis, designing an experiment, collecting data, analyzing results, and drawing a conclusion.
This document provides an overview of the scientific inquiry process. It discusses the key steps, which include identifying a problem or question, collecting background information, forming a testable hypothesis, conducting an experiment to test the hypothesis, analyzing the results, and drawing a conclusion. The document also defines important scientific concepts like variables, controls, and different types of data. The overall goal of the scientific inquiry process is to gather evidence and determine relationships between factors through reliable and repeatable experiments.
Here is how I would design the experiment:
- Control Group: 2 patients who do not receive the drug. This group acts as the standard for comparison.
- Experimental Group: 4 patients who receive the new drug.
- Independent Variable: Whether or not the patient receives the new drug. This is what is being manipulated.
- Dependent Variable: The growth of breast cancer in the patients, as measured by tumor size. This variable depends on and is expected to change due to the independent variable.

Scientific research is an organized, objective, controlled, qualitative or quantitative empirical analysis of one or more factors. The terms that define the scientific research method describe a procedure that has been accepted for centuries.
Six basic characteristics, or tenets, distinguish the scientific method from other methods of knowing. A research approach that does not follow these tenets is not a scientific approach.
This document describes the process of scientific inquiry. It begins with making observations and asking questions, then developing a testable hypothesis and designing an experiment to test the hypothesis. The experiment involves collecting and interpreting data, then drawing a conclusion about whether the data supports the original hypothesis. The process may lead to new questions and further inquiry. Communicating results is also an important part of the scientific process.
This document summarizes key concepts from Chapter 3 of the textbook "The Personality Puzzle" regarding research methods in personality psychology.

Experimental and quasi experimental researchNova Isnawati
This document discusses experimental and quasi-experimental research methods. Experimental research methods aim to test the effect of a treatment in uncontrolled conditions and allow strict control of variables. Quasi-experimental designs involve selecting groups to test a variable without random assignment and cannot fully control external factors. Both methods are useful in social sciences where random assignment is difficult. Experimental research advantages include control over external factors, while disadvantages include potential lack of randomization. Quasi-experiments reduce time/resources compared to experiments but cannot account for pre-existing influences as well.

SDSS1335+0728: The awakening of a ∼ 106M⊙ black hole⋆Sérgio Sacani
Context. The early-type galaxy SDSS J133519.91+072807.4 (hereafter SDSS1335+0728), which had exhibited no prior optical variations during the preceding two decades, began showing significant nuclear variability in the Zwicky Transient Facility (ZTF) alert stream from December 2019 (as ZTF19acnskyy). This variability behaviour, coupled with the host-galaxy properties, suggests that SDSS1335+0728 hosts a ∼ 106M⊙ black hole (BH) that is currently in the process of ‘turning on’. Aims. We present a multi-wavelength photometric analysis and spectroscopic follow-up performed with the aim of better understanding the origin of the nuclear variations detected in SDSS1335+0728. Methods. We used archival photometry (from WISE, 2MASS, SDSS, GALEX, eROSITA) and spectroscopic data (from SDSS and LAMOST) to study the state of SDSS1335+0728 prior to December 2019, and new observations from Swift, SOAR/Goodman, VLT/X-shooter, and Keck/LRIS taken after its turn-on to characterise its current state. We analysed the variability of SDSS1335+0728 in the X-ray/UV/optical/mid-infrared range, modelled its spectral energy distribution prior to and after December 2019, and studied the evolution of its UV/optical spectra. Results. From our multi-wavelength photometric analysis, we find that: (a) since 2021, the UV flux (from Swift/UVOT observations) is four times brighter than the flux reported by GALEX in 2004; (b) since June 2022, the mid-infrared flux has risen more than two times, and the W1−W2 WISE colour has become redder; and (c) since February 2024, the source has begun showing X-ray emission. From our spectroscopic follow-up, we see that (i) the narrow emission line ratios are now consistent with a more energetic ionising continuum; (ii) broad emission lines are not detected; and (iii) the [OIII] line increased its flux ∼ 3.6 years after the first ZTF alert, which implies a relatively compact narrow-line-emitting region. Conclusions. We conclude that the variations observed in SDSS1335+0728 could be either explained by a ∼ 106M⊙ AGN that is just turning on or by an exotic tidal disruption event (TDE). If the former is true, SDSS1335+0728 is one of the strongest cases of an AGNobserved in the process of activating. If the latter were found to be the case, it would correspond to the longest and faintest TDE ever observed (or another class of still unknown nuclear transient). Future observations of SDSS1335+0728 are crucial to further understand its behaviour. Key words. galaxies: active– accretion, accretion discs– galaxies: individual: SDSS J133519.91+072807.4

Compositions of iron-meteorite parent bodies constrainthe structure of the pr...Sérgio Sacani
Magmatic iron-meteorite parent bodies are the earliest planetesimals in the Solar System,and they preserve information about conditions and planet-forming processes in thesolar nebula. In this study, we include comprehensive elemental compositions andfractional-crystallization modeling for iron meteorites from the cores of five differenti-ated asteroids from the inner Solar System. Together with previous results of metalliccores from the outer Solar System, we conclude that asteroidal cores from the outerSolar System have smaller sizes, elevated siderophile-element abundances, and simplercrystallization processes than those from the inner Solar System. These differences arerelated to the formation locations of the parent asteroids because the solar protoplane-tary disk varied in redox conditions, elemental distributions, and dynamics at differentheliocentric distances. Using highly siderophile-element data from iron meteorites, wereconstruct the distribution of calcium-aluminum-rich inclusions (CAIs) across theprotoplanetary disk within the first million years of Solar-System history. CAIs, the firstsolids to condense in the Solar System, formed close to the Sun. They were, however,concentrated within the outer disk and depleted within the inner disk. Future modelsof the structure and evolution of the protoplanetary disk should account for this dis-tribution pattern of CAIs.
Embracing Deep Variability For Reproducibility and Replicability
Abstract: Reproducibility (aka determinism in some cases) constitutes a fundamental aspect in various fields of computer science, such as floating-point computations in numerical analysis and simulation, concurrency models in parallelism, reproducible builds for third parties integration and packaging, and containerization for execution environments. These concepts, while pervasive across diverse concerns, often exhibit intricate inter-dependencies, making it challenging to achieve a comprehensive understanding. In this short and vision paper we delve into the application of software engineering techniques, specifically variability management, to systematically identify and explicit points of variability that may give rise to reproducibility issues (eg language, libraries, compiler, virtual machine, OS, environment variables, etc). The primary objectives are: i) gaining insights into the variability layers and their possible interactions, ii) capturing and documenting configurations for the sake of reproducibility, and iii) exploring diverse configurations to replicate, and hence validate and ensure the robustness of results. By adopting these methodologies, we aim to address the complexities associated with reproducibility and replicability in modern software systems and environments, facilitating a more comprehensive and nuanced perspective on these critical aspects.

• Dependent variable – is a responding factor that may change as a
result of changes made in the independent variable (the y-axis)
• Control group – serves as the standard comparison in all
experiments. It is exposed to the same conditions as the
experimental group except for the variable being tested.
23. 6. Gathering data and interpreting results
• Record what happened.
• This can be presented in the form of a table of processed numerical
data, or graphs.
• It could also be a written statement of what occurred during
experiments.
• It is from calculations using recorded data that tables and graphs are
made.
• Studying tables and graphs, we can see trends that tell us how
different variables cause our observations.
24. 7. Draw conclusion
• Using the trends in your experimental data and your experimental
observations, try to answer your original questions.
• Is your hypothesis correct?
• Now is the time to pull together what happened, and assess the
experiments you did.
• You can make recommendations to your conclusion.
25. • If your hypothesis is not correct, what could be the answer to your
question?
• Summarize any difficulties or problems you had experimenting with.
• Do you need to change the procedure and repeat your experiment?
• What would you do differently next time?
• List other things you learned.

42. •Observations can be Qualitative when using
your senses to observe the results. (Sight, smell,
touch, taste and hear.)
•Quantitative observations are made with
instruments such as rulers, balances, graduated
cylinders, beakers, and thermometers. These
results are measurable.
43.
44. •What is a variable?
•A Variable is any factor that can change in a
scientific investigation or experiment.
45. There are three types of variables:
•1. Independent variable (also called the
manipulated variable)
•• The condition that is intentionally changed by
the investigator in an experiment.
•• There can be only one independent variable in
an experiment.
46. •2. Dependent variable (also called the responding
variable)
•The factors or conditions that will change as a
result of the independent variable.
• These are the factors that you measure or observe
as data.
•There can be one or more dependent variables in an
experiment.
47. •3. Controlled variables
•The factors or conditions that are kept
the same (unchanged) in an experiment
• There are many controlled variables in
an experiment.
48. Let us try identifying variables in
the following experiments:
49. • Problem: Does changing the temperature of a ball
affect the height of the ball will bounce?
Independent Variable
Dependent Variable
• Controlled variable: same ball, dropped from
the same height and surface
50. 1st setup: red light
2nd setup: white light
3rd setup: blue light
Does changing the color of light affects the
growth rate of plants?
51. Directions: Identify the independent, dependent,
and controlled variable in the following problems
below:
• IV:_______________________
• DV:_______________________
• CV:_______________________
52. Directions: Identify the independent, dependent, and
controlled variable in the following problems below.
•1. Does the amount of butter in a popcorn
kernels affect the amount of popcorns that pop?
•2. What happens to the speed of a marble
travels when the height of a ramp is changed?
•3.How do different style pencils or grips affect
writing fatigue?
•4. How does photo editing affect
•perception?
53. Do Now! In which situation it is important to
make a hypothesis?
54. It is important to understand the following
concepts in any scientific investigation:
• 1. Scientists rely on using their senses to make
observations in order to construct hypotheses.
• 2. A working hypothesis generates
expectations/predictions that can be tested
(variables).
• 3. Additional information (more observations) can
alter and/or refine hypotheses and expectations.
55. • 4. A hypothesis is usually written in a form where it
proposes that if something is done, then something
else will occur. To write a hypothesis:
• Identify what the problem is.
• Make a hypothesis as to what direction of the
relationship or difference is. It is necessary because it
provides an initial explanation to your observation.
• Identify the major variables such as the independent
(manipulative)variable, the dependent (responding)
variable, and the control group (serves as the standard
comparison and no treatment is applied)
56. • A hypothesis needs to be specific and objective. Avoid
using better than, bigger than, a little more than,
sometimes, a lot, greater than will occur more often
than.
• The format of writing a hypothesis is… If (variables),
then (predict the outcome of the experiment using
the dependent variable).
57. •Example: Chocolate may cause acne (observation)
•A hypothesis using the “if, then” format.
•If a person’s incidence of having an acne is related
to the amount of chocolate a person consumes,
then the incidence of acne will be 20% higher
when a person consumes a large amount of
chocolate (3 chocolate bars per day) than when the
person consumes little or no chocolate.
58. • OBSERVATION 1: One time Mr. Alvarez went to the
grocery store and he bought all the types of
microwave popcorn that the store had. With these
types of popcorn, he conducted an experiment.
• PROBLEM: Does the amount of butter in a popcorn
kernels affect the amount of popcorns that pop?
• HYPOTHESIS: If Mr. Alvarez put 1 tablespoon of butter,
2 tablespoon butter, and 3 tablespoon butter in each
20 grams popcorn kernel, then all the popcorn kernels
will pop in each sample.
59. •OBSERVATION 2: Aljune and Toby proposes the
idea that the marble would travel at a faster
pace if it is rolled down the longer slide.
•PROBLEM: What happens to the speed of a
marble travels when the height of a ramp is
changed?
• HYPOTHESIS: If the height of a ramp is doubled,
then the marble will reach the same speed even
if the inclined is increased.
60. Activity 2. Create a hypothesis based
on a sample observation. Use the “if,
then” style or format and include a
measurable condition.
61.
62. It is important to remember that a hypothesis
should always:
• Explain what you expect to happen
• Be clear and understandable
• Be testable
• Be measurable
• Contain and independent and dependent
variable
63. Designing a simple investigation involves the
following criteria:
• 1. Be observable and ask questions that are testable.
• 2. Properly identify the independent, dependent and control
variables in an experiment.
• 3. Collect, organize and interpret data qualitatively and/or
quantitatively.
• 4. Make sure to list on your journal all your findings from the
beginning up to the last part of the investigation.
• 5. If you reject a hypothesis, make sure to do retesting of your
experiment.
• 6. Make a final statement of your accepted hypothesis.
64. 1. When should you make a hypothesis?
•a. Before you do an experiment
•b. While you do an experiment
•c. After you do an experiment
•d. There is no good time to make an
experiment
65. •2. Which of the following is NOT a rule when
writing a hypothesis?
•A. It is testable
•B. It is a prediction
•C. It is an if/then statement
•D. it should restate the question.
