Why would there be different published values for the normal range of a particular measurement?
Different people or organizations may have made slightly different measurements. Measurements are never 100% accurate.
What does a line graph in which the data points do not fall along a straight line mean?
There are several possible answers: The line is actually meant to be a curved line and not a straight line. The relationship between the two variables is not a linear function. Discovering this can be one of the main reasons for drawing the graph. The data points are empirical measurements (from an experiment, for example) and there are errors associated with the observations. The errors may be systematic or random. You have made mistakes - either in recording the data or in plotting them.
When is data considered invalid?
Data is considered invalid when it is wrong or has changed. Data represents facts that are recorded, so any alterations made to it can make it invalid.
What trend can you see in the graph you made from the data table about the distance traveled by a car?
That question can only be answered by the person who made the graph from the data table, referred to as "you" in the question. Get busy!
Explain the different stages of planning a statistical survey?
Stages of Planning a statistical survey 1. Nature of the problem to be investigated should be clearly defined in an un-ambigous manner. 2. Objectives of investigation should be stated at the outset. Objectives could be to obtain certain estimates or to establish a theory or to verify a existing statement to find relationship between characteristics etc. 3. The scope of investigation has to be made clear. It refers to area to be covered, identification of units to be studied, nature of characteristics to be observed, accuracy of measurements, analytical methods, time, cost and other resources required. 4. Whether to use data collected from primary or secondary source should be determined in advance. 5. The organization of investigation is the final step in the process. It encompasses the determination of number of investigators required their traning, supervision work needed, funds required.
What word means measurements made during an experiment?
Data
Which conclusion can best be made from these measurement?
It would depend on the specific measurements you are referring to. Generally, conclusions should be made based on a careful analysis of the data and consideration of relevant factors.
What do you call the results of an experiment?
Observations and measurements made during an experiment are called the data.
What are the most common measurements made in the lab?
Some common measurements made in the lab include mass, volume, temperature, pH, and concentration. These measurements are essential for conducting experiments, analyzing data, and ensuring accuracy in scientific research.
What is a observation made with measurements?
An observation made with measurements involves quantifying a certain characteristic or property of an object, event, or phenomenon using numerical values. These measurements provide concrete data that can be analyzed and compared to draw conclusions or identify patterns in the observed behavior.
Is the Observation made during an Experiment are called data?
Yes, observations made during an experiment are referred to as data. Data can include measurements, descriptions, and other information collected during the experiment to support analysis and conclusions.
Why are many scientific observations made in the form of measurements?
Scientific observations are often made in the form of measurements because measurements provide quantitative data that can be used to analyze and understand natural phenomena objectively. Measurements allow researchers to record and compare data, test hypotheses, and make predictions based on empirical evidence. By quantifying observations, scientists can establish patterns, relationships, and principles that form the foundation of scientific knowledge.
When will scientists make measurements?
Scientists continuously make measurements as part of their research and experiments. The timing of measurements depends on the specific research question being addressed and the experimental design. Measurements can be made at various stages of a study to collect data and draw conclusions about the phenomenon being studied.
What problems could result from incorrectly converting measurements from the system to another?
Incorrectly converting measurements from one system to another could result in errors in calculations, leading to inaccurate data and potentially incorrect decisions being made based on that data. This can cause misunderstandings, inefficiencies, and even safety hazards in fields where precise measurements are crucial, such as science, engineering, and construction.
What should you do if your data are different from what you expected?
Conclude that you made a mistake in the way you collected the data
Which of the following describes a reason for making a prediction when doing a controlled experiment?
To indicate what specific results will support a hypothesis to anticipate the observations or measurements that will be made apex
What is telemtry?
Telemetry is the highly automated communications process by which measurements are made and other data collected at remote or inaccessible points and transmitted to receiving equipment for monitoring
