Research Methods Cheat Sheet

1. Quantitative Research

Purpose: To measure variables, test hypotheses, and generalize findings using numerical data.

Key Features:

  • Uses large, statistically significant samples
  • Employs structured tools like surveys, experiments, or questionnaires
  • Focuses on “how many,” “how often,” or correlations between variables
  • Analysis is statistical

Strengths:

  • Standardized and replicable
  • Can generalize findings
  • Allows identification of patterns and trends


Limitations

Mode of Occurrence of Igneous Rocks:- Igneous rocks are formed by the cooling and solidification of molten magma either beneath the Earth’s surface or on it. Their mode of occurrence is closely related to the depth of crystallization, the nature of magma intrusion, and the environment in which the magma solidifies. Broadly, igneous rocks occur in two main modes: intrusive (plutonic) and extrusive (volcanic).

Intrusive (Plutonic) Igneous Rocks:

These rocks form when magma cools slowly beneath the

Practicle

Activity:-

To observe deflection of a magnetic needle placed near a conductor carrying current.

Apparatus and materials:

Magnetic needle, battery, ammeter, rheost, key, conducting wire etc.

Theory:

When electric current passes through a conductor magnetic field is produced around it.

Procedure:

(1) Magnetic substances are removed from the table and the magnetic needle is placed on it. The cell, rheostat, key and ammeter are connected in series with the experimental wire as shown in Fig. 37. The

Experiment 6

Aim- to determine refractive index of a material of a glass slab by pin method.

Apparatus and material:- glass slab, drawing board, drawing pina, hair pins ,paper, scale and protractor.

Theory:-The refractive index, n of glass with respect to air is defined as-n = sin i / sin r

where i is the angle of incidence and r is the angle of refraction. Thus a graph plotted with sin r along X-axis and sin i along Y-axis will be a straight line passing through the origin. The slope of the graph

Practical

To observe the variation of potential difference (V) across a given resistance with varying current (I) and draw I-V curve and find the value of a given resistance from graph.

Apparatus and materials:
Battery, ammeter, voltmeter, resistance, rheostat, key, connecting wires and sand paper.
Theory:
Ohm's law states that the temperature remaining constant the current (1) flowing through a conductor is proportional to the voltage (V) across it. Thus,   
I∞V
or, V = IR
where R is called the resistance

NLP

NLP – Definition & Applications 

Natural Language Processing (NLP) is a branch of Artificial Intelligence (AI) which helps computers to understand, analyze and generate human language (text or speech).

 NLP is a bridge between human language and computer language.

Applications of NLP (Explain any Four)

1. Machine Translation

Machine Translation converts text from one language to another automatically using NLP.

Example: Google Translate
Use: Helps people communicate in different languages.

Hoy vamos a describir el tiempo en Suecia usando una mapa del tiempo.

En el norte de Suecia, por ejemplo en Kiruna y Luleå, hace mucho frío. En Kiruna está nublado y nieva, y la temperatura es muy baja. En Luleå también hace frío y está nublado. En Tärnaby, en el norte, nieva y hace frío.

En el centro de Suecia, el clima es un poco diferente. En Östersund está nublado y hace frío. En Umeå hace frío, pero hay sol. En Sundsvall hay sol y hace un poco de calor. En Mora también hace sol

Inledning

Romanen När hundarna kommer av Jessica Schiefauer handlar inte bara om brott, sorg och skuld, utan också om relationer och hur kärlek kan förändras till något destruktivt. Ett av de tydligaste temana i boken är kärlek och beroende, som framför allt skildras genom relationen mellan Ester och Isak. Deras förhållande börjar som en intensiv och romantisk tonårskärlek, men utvecklas gradvis till ett osunt känslomässigt beroende. I stället för att relationen ger trygghet och
