Data is information that is interpreted by a collection (Representation) of explanatory words or symbols. A simple explanation is a 60mph sign at the side of the road. The figure 60 is the data while the sign embossed with 60 is the representation informing you of that which you need to know. Traffic lights are a representation that tells you by the data of different colours what you you need to know. @ is a representation of the data "at"
What else can I help you with?
Is it possible for a coefficient of variation to be negative Explain.?
Of course it is! If the mean of a set of data is negative, then the coefficient of variation will be negative.
How mean of a data set is always one of the data points in a set of data. Explain?
The mean of a set of data is the sum of all those data values, divided by the numbers of values in the set. For instance, if we had 1, 3 and 5, the mean would be (1+3+5)/3 = 3. The mean doesn't always have to be one of the data points in the set. For instance, if we had the data 1, 6, 7, 7, 8. The mean would be (1+6+7+7+8)/5 = 5.8, even though 5.8 isn't one of the values in the set.
What can a standard deviation tell us about the usefulness of the mean?
Standard deviation measures the dispersion or variability of data points around the mean. A low standard deviation indicates that the data points are closely clustered around the mean, suggesting that the mean is a reliable representation of the dataset. Conversely, a high standard deviation signifies greater variability, which may diminish the mean’s usefulness as a summary statistic, as it may not accurately reflect the data's central tendency. Thus, understanding standard deviation helps assess how well the mean represents the underlying data.
What does sensory data mean?
Its mean incomplete data or the data upon which we can not rely totally.
What do mean by Data Handling?
what do you mean by data handling define mean mode median
Why is mean used as an indicator in measurement?
Since the mean is the average of all your data, it is a good representation of the data as a whole, and it is much easier to look at one number than to have to deal with multiple pieces of data.
What is bar bench and hearsay Please explain briefly with points?
The bar bench and hearsay mean that where is no return value. This is to void hello in points.
Why is an average or mean important?
They are the same thing. They give you an accurate representation of all the values in a data set
Explain why the mean does not best represent the data?
well because in the mean you have to add them and its different from the median and the mode
Explain briefly once you are not informed you are automatically deformed?
If you are not informed you, it would mean that you are uninformed or under informed in a topic. Deformed is used in the wrong context.
What does write a speech to explain your position on the representation issue mean?
Presumably this is homework you have been assigned. Read the question. You are supposed to write a speech. The topic of the speech is the "representation issue." You are expected to have a position (or opinion) about the issue. Possibly your position is something as simple as being either in favour or opposed to "representation." Spend a little time reading about the "representation issue." What does it mean? Is it good or bad (from your point of view)? Form your opinion (i.e., take a position). Now, write a speech explaining your position. Maybe you are trying to convince others to agree with your point of view. Maybe you are trying to justify why you supported it or opposed it. Hint: it might help if you start your speech by explaining what "the representation issue" is all about, if you next discuss the good things and the bad things about it, if you briefly state that you have made a decision to support (or oppose) it, and then explain why you have decided to do so (and why others should do so too). All right. Let's get started. What is the meaning of the "representation issue?"
Are data and information may mean the samething explain?
Information is stored in data, which is a collection of information. Strictly speaking, a datum (singular form of data) is a single unit of information.
Why do scientist use graphs when analyzing data?
Scientists use graphs while analyzing data to give a graphical or image based representation of the data that is more easily understandable as compared to the complex tabular or numerical data. Graphs make patterns and repetitions more obvious, and also clearly demonstrate deviations from the mean.
The mean score for a test is 88 One more score is added the data Is it possible for the mean to remain 88 Explain?
176
What does it mean to state briefly?
State
Is it possible for a coefficient of variation to be negative Explain.?
Of course it is! If the mean of a set of data is negative, then the coefficient of variation will be negative.
Whats the mean of a set of data and explain how to find it?
take the sum of all the numbers ∑xand divide it by the number of numbers in the data set. nor ∑x/n
