Several observations are taken for each measurement to eliminate or decrease the margin of error.

Why are several trials taken for each measurement in an experiment?
A good way to reduce error or increase measurement accuracy is to take several measurements and compute their average. In other words, you achieve accuracy through averaging. (This also validates the repeatability of the measurement.)
What are the two kinds of observation describe each?
qualitative observation and quantitative observation
How do you construct a multivariate table?
Draw up a table with several columns, each representing a variable. Each row in the table is an observation, with data stretching across the columns.
What is a standardized unit that tells how far away each measurement is from the mean?
Standard deviation is a measure of the spread of data around the mean. The standardized value or z-score, tells how many standard deviations the measurement is away from the mean, and in which direction.z score = (observation - mean) / standard deviationStandard deviation is the unit measurement. This tells what the value a decimal is.
How close a series of measurement are to each other?
Precision
What are the different kinds of observation?
There are several types of observation, including naturalistic observation, where researchers observe subjects in their natural environment without interference; participant observation, where the observer becomes part of the group being studied; and controlled observation, which occurs in a structured setting where variables can be manipulated. Other types include systematic observation, focusing on specific behaviors, and longitudinal observation, which tracks changes over time. Each type serves different research purposes and offers unique insights into behavior and interactions.
Why several measurement are taken for each quantity in an eperiment?
Taking multiple measurements for each quantity helps to ensure accuracy and reliability of the data by reducing the impact of random errors. Averaging multiple measurements can provide a more representative value and reduce the effect of outliers or anomalies. It also allows for assessing the precision of the measurements by calculating the standard deviation or uncertainty.
What is each observation of an experiment?
It could be viewed as a trial.
What is the measurement of each base angle?

What is meant by measurement is accurate but not precise?
An accurate but not precise measurement would be an approximate measurement. For example, in cooking or baking, the ingredients list might indicate one cup of a certain item. Scientifically, however, one cup, (or 8 ounces) would not be a precise measurement for testing purposes. Instead, a precisemeasurement would be required, especially when the results of a specific test need to be reproducible and the quantities are minute, as in micrograms, for example. Accuracy in measurement is of closeness to the actual or exact, but precision in measurement is closeness to the same spot each time it is taken.
What is the measurement of 2 in the parallelogram when 1 and 3 are each 35 degrees?
The measurement of 2 in the parallelogram when 1 and 3 are each 35 degrees is 145 degrees.
What is the difference between observation and survey?
The words, observation and survey, each have several different meanings, but they also have a meaning that is similar. One definition of observation and survey is the act of observing, looking or seeing. Another definition for observation is the act of noticing something. Another definition for survey is the act of making an inspection.
