No, for example the set of data 15,20,26,28 has a median that is 20 + 26 /, or 23
No. Here's one set of data where the mean is not one of the values: a set of 250,000 numbers. 125,000 of them are "1", 125,000 are "3". The mean of this data set is "2", which is not among the data.
one set of data values increases as the other decreases
There are five values with one missing. The original set had six values with a mean of 5, which means that the members of the set added up to thirty. The values we have total 19, the missing value is 11.
yes they are if you have 0 and 10 the mean is 5 and so is the median. The mean and the median can in fact be the same value. But basically to answer your question, One possible way is that if the values are ascending by 1 in the data set, then the number of values left to the median should be the same as the number of values right to the median. e.g. 6+7+8+9+10 6,7 = 2 terms 9,10 = 2 terms median =8 mode = 8
One variable data are measurements or recordings of the values of one characteristic of the subjects which are being studied. Two variable data refer to two characteristics. Examples of one variable data: hair colour, or height Examples of two variable data: hair colour and eye colour, or height and mass.
No. Here's one set of data where the mean is not one of the values: a set of 250,000 numbers. 125,000 of them are "1", 125,000 are "3". The mean of this data set is "2", which is not among the data.
Not all the time
34.1% of the data values fall between (mean-1sd) and the mean.
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.
The Empirical Rule states that 68% of the data falls within 1 standard deviation from the mean. Since 1000 data values are given, take .68*1000 and you have 680 values are within 1 standard deviation from the mean.
yes/no data type stores only one oftwo values
one set of data values increases as the other decreases
Analogue data is data in a continuous stream that has an infinite range of values that change gradually. One example of analogue data is the sound of a person talking. We are capable of handling analogue data, yet computers require analogue data to be converted into digital data for processing.
I'm not completely sure what you mean. But I can tell you how to find the mean, if that is what you are looking for. You must add up all your numbers (4+2+1) and then take you answer and divide it by the number of numbers you added together (7 divided by 3) The quotient is your answer. Hope I was a help
MEDIANUse the median to describe the middle of a set of data that does have an outlier.Advantages:• Extreme values (outliers) do not affect the median as strongly as they do the mean.• Useful when comparing sets of data.• It is unique - there is only one answer.Disadvantages:• Not as popular as mean.
A data series is a range of values to be charted. If you have multiple data values, you may have multiple series, like several lines on a line chart. So you can have lots of values in a series, and lots of series in some charts. A pie chart cannot have more than one series. Data can be of various types.A data series is a range of values to be charted. If you have multiple data values, you may have multiple series, like several lines on a line chart.
