What is a data logger?
A data logger is an electronic device that gathers and stores data from sensors, which can then be processed by a computer.
What is the role of electronic sensors in data collection?
Electronic sensors detect changes in their surroundings, converting this information into electrical signals stored by data loggers.
True or False?
Data loggers can calculate averages and plot graphs more efficiently than humans.
True.
Data loggers can process data into tables, calculate averages and plot graphs quickly and accurately.
What is a pH meter used for?
A pH meter measures the acidity or alkalinity of a solution, expressed as a pH value.
What is a scientific database?
A database is a structured collection of data that can be searched, sorted, filtered and analysed quickly.
What role do models and simulations play in biological investigations?
Models and simulations can be used to:
generate data via a computer simulation
make predictions about real-life scenarios
carry out small-scale investigations to inform the planning of larger studies
True or False?
Data loggers are useful for environmental monitoring due to their ability to take continuous readings.
True.
Data loggers allow for the continuous monitoring of environmental parameters, such as temperature or pH, over time.
How can a spreadsheet be used for data analysis in biology?
A spreadsheet is used to record, manipulate, and organise data into columns and rows.
The data can then be used to produce graphs and carry out further calculations or statistical analysis.
True or False?
Spreadsheets can be used to store data but not to perform calculations.
False.
Spreadsheets can store data and perform calculations. They can also enable statistical analysis and create visualisations.
What is the purpose of presenting data as a graph?
The purpose of presenting data in graphs is to easily identify patterns, correlations and trends.
True or False?
Computers can automatically generate graphs from raw data.
True.
Computers can automatically generate graphs from raw data using built-in functions in spreadsheet software.
What is computer modelling?
Computer modelling involves carrying out simulated experiments in order to understand complex processes and make predictions about real-life biological systems.
How can technology be used in image analysis?
Technology can be used in image analysis for, e.g.:
simulating movement of biological structures
measuring biological structures
identifying abnormalities in medical images
