Is it possible not to have a hypothesis in your thesis?
There are fields - especially in Engineering - where results do not depend on a statistical analysis so as non-statistician, I would say, yes you can write a thesis without a hypothesis. - o4tlulz.

Null hypothesis
In scientific research, the null hypothesis (often denoted H 0) [1] is the claim that the effect being studied does not exist. [note 1] The null hypothesis can also be described as the hypothesis in which no relationship exists between two sets of data or variables being analyzed.If the null hypothesis is true, any experimentally observed effect is due to chance alone, hence the term "null".
Null & Alternative Hypotheses
The null and alternative hypotheses are two competing claims that researchers weigh evidence for and against using a statistical test: Null hypothesis (H0): There's no effect in the population. Alternative hypothesis (Ha or H1): There's an effect in the population. The effect is usually the effect of the independent variable on the ...
What Is The Null Hypothesis & When To Reject It
Usually, a researcher uses a confidence level of 95% or 99% (p-value of 0.05 or 0.01) as general guidelines to decide if you should reject or keep the null. When your p-value is less than or equal to your significance level, you reject the null hypothesis. In other words, smaller p-values are taken as stronger evidence against the null ...
How to Write a Strong Hypothesis
6. Write a null hypothesis. If your research involves statistical hypothesis testing, you will also have to write a null hypothesis. The null hypothesis is the default position that there is no association between the variables. The null hypothesis is written as H 0, while the alternative hypothesis is H 1 or H a.
PDF Research Questions and Hypotheses
null hypothesisrepresents the traditional approach: it makes a predic-tion that in the general population, no relationship or no significant differ-ence exists between groups on a variable. The wording is, "There is no difference (or relationship)" between the groups. The following example illustrates a null hypothesis. Designing Research
Research questions, hypotheses and objectives
Research hypothesis. The primary research question should be driven by the hypothesis rather than the data. 1, 2 That is, the research question and hypothesis should be developed before the start of the study. This sounds intuitive; however, if we take, for example, a database of information, it is potentially possible to perform multiple ...
Hypothesis: Definition, Examples, and Types
A hypothesis is a tentative statement about the relationship between two or more variables. It is a specific, testable prediction about what you expect to happen in a study. It is a preliminary answer to your question that helps guide the research process. Consider a study designed to examine the relationship between sleep deprivation and test ...

Research Methodology: Is it mandatory for all researches to have a
The answer is "no". There are various established traditions in research that call for distinct methodologies, strategies and practices. The formulation of one or more hypotheses is a practice ...
Research Questions & Hypotheses
The primary research question should originate from the hypothesis, not the data, and be established before starting the study. Formulating the research question and hypothesis from existing data (e.g., a database) can lead to multiple statistical comparisons and potentially spurious findings due to chance.

From what you've written, your hypothesis is that. you can tailor the [information-systems] management theory for it to be useful under economic constraints to a real specific problem. You might also be doing exploratory research, or blue-skies research, where you don't start with a research question, you start with a ...
Research Hypothesis In Psychology: Types, & Examples
Examples. A research hypothesis, in its plural form "hypotheses," is a specific, testable prediction about the anticipated results of a study, established at its outset. It is a key component of the scientific method. Hypotheses connect theory to data and guide the research process towards expanding scientific understanding.
A hypothesis can't be right unless it can be proven wrong
A good scientific hypothesis is the opposite of this. If there is no experimental test to disprove the hypothesis, then it lies outside the realm of science. Scientists all too often generate hypotheses that cannot be tested by experiments whose results have the potential to show that the idea is false.
What Is A Research Hypothesis? A Simple Definition
A research hypothesis (also called a scientific hypothesis) is a statement about the expected outcome of a study (for example, a dissertation or thesis). To constitute a quality hypothesis, the statement needs to have three attributes - specificity, clarity and testability. Let's take a look at these more closely.
Hypotheses
An hypothesis is a specific statement of prediction. It describes in concrete (rather than theoretical) terms what you expect will happen in your study. Not all studies have hypotheses. Sometimes a study is designed to be exploratory (see inductive research). There is no formal hypothesis, and perhaps the purpose of the study is to explore some ...
Research Problems and Hypotheses in Empirical Research
Research problems and hypotheses are important means for attaining valuable knowledge. They are pointers or guides to such knowledge, or as formulated by Kerlinger (1986, p. 19): " … they direct investigation.". There are many kinds of problems and hypotheses, and they may play various roles in knowledge construction.
What is a hypothesis?
A hypothesis states your predictions about what your research will find. It is a tentative answer to your research question that has not yet been tested. For some research projects, you might have to write several hypotheses that address different aspects of your research question. A hypothesis is not just a guess — it should be based on ...
Step-by-Step Guide: How to Craft a Strong Research Hypothesis
Hypotheses in research need to satisfy specific criteria to be considered scientifically rigorous. Here are the most notable qualities of a strong hypothesis: Testability: Ensure the hypothesis allows you to work towards observable and testable results. Brevity and objectivity: Present your hypothesis as a brief statement and avoid wordiness.
