What is grouped frequency distribution?
If the observations are grouped together into classes, then the number of observations for each class gives the grouped frequency distribution (FD). This kind of FD is particularly important when the data are continuous so that you are likely to have very small frequencies for a very large number of values.
What do you call data if organized with several values together?
Grouped data.
What is continuous grouped data?
In continuous grouped data the data is collected continuously and in groups. Data collected is in class intervals the actual data values are not visible.
What is the interquartile range in math?
The interquartile range (IQR) is a measure of spread in statistics. The observations (data) are arranged in order of magnitude - usually smallest to largest.Suppose there are n observations. Then calculate (n+1)/4 and round it to m, say. For large n (>30) don't bother with the +1 Then find the values of the observations is positions m and 3m. [That last sentence would be so much simpler if this crap browser allowed superscripts but mth and 3mth is confusing!] The number in position m is called the "Lower Quartile" and a quarter of the observations are smaller than it is. The number in position 3m is called the "Upper Quartile" and a quarter of the observations are greater than it is. The difference between the two values (not m and 3m but the values of the observations in those positions) is the IQR.Since a quarter of the observations are smaller than the LQ and a quarter are larger than the UQ, the IQR contains the middle half of all observations.
What is quantative analysis?
It is a typographical error. A quantitative analysis is one in which the observations have numeric values.

What does GroupData mean?
Rather than have frequencies of observations allocated to each observed value, grouped data allocates them to a range (or group) of values.
What does it means if the standard deviation is small?
Simplest terms, it means that the sample values are grouped closely together. Another way of saying it is that the range of values is small. The plot will be a leptokurtic plot (peaked).
If data are organized with several values together the result is?
The result is a collection of grouped data.
What do you call data if organized with several values together?
Grouped data.
What is the main difference qualitative and quantitative observations?
The first will have numerical values associated wit the observations the second will not.
What is continuous grouped data?
In continuous grouped data the data is collected continuously and in groups. Data collected is in class intervals the actual data values are not visible.

A grouped frequency distribution is used when the range of data values is relatively small. True or false?
False. When the range is large you would use a grouped frequency distribution.
How do you get the moyenne?
You add together the values observed and divide the sum by the number of observations.
To look at known values and make an estimation based on observations is called what?
hdheheh
What is the properties of mode?
The mode is a measure that appears most often in a set of observations. It can be used with qualitative data whereas the other traditional measures of "central tendency" cannot. Also, by its very definition, it must be a value that is observed. However, for grouped data, the mode is very dependent on the grouping values.
