What interval would be appropriate to graph data?
Hourly temperature
What is mean data?
Mean data are observations whose values are equal to the mean of the data set. By default it is the arithmetic mean but it could be the geometric or harmonic mean - if those measures are more appropriate.
What is the data that is comprised of numerical values?
interval data
What is the appropriate measures of central tendency for ratio data?
iDK! do your homework! or even better! pay attention in class! i learned that the hard way.
How does mean median and mode apply in life?
They are statistical measures that are used, when appropriate, to summarise the central tendency of a set of data. That is, given a number of observations, these measures can give an indication of the value near which they all are.
For interval ratio data the correct measure of central tendency is?
Interval-Ratio can use all three measures, but the most appropriate should be mean unless there is high skew, then median should be used.
What interval would be appropriate to graph data?
Hourly temperature
What interval would be appropriate to graph the data?
The time and the temperature
What is the pattern of a variability within a data set called?
The range, inter-quartile range (IQR), mean absolute deviation [from the mean], variance and standard deviation are some of the many measures of variability.
What is an appropriate scale and interval for a data set in a table?
The answer will depend on the data values: there is no rule that fits all situations.
What two data characteristics are usually measured using numerical descriptive measures?
Variability and Central Tendency (Stats Student)
How does finding the IQR hep you identify the variability of set of data?
The IQR gives the range of the middle half of the data and, in that respect, it is a measure of the variability of the data.
Which is an appropriate display to show the measures of variation for a data set?
There are a number of appropriate displays to show the measures of variation for a data set. Different graphs can be used for this purpose which may include histograms, stemplots, dotplots and boxplots among others.
Is elevation interval data or ratio?
interval
What is the sources of variability in a stats graphs?
the whole question is that The data is not perfectly linear. Identify at least 2 sources of variability in this data AND explain the effect of each? Sources of variability = outlier???? so do I just need to indicate where the outliers are???
What measures are used to describe variability?
Generally, the standard deviation (represented by sigma, an O with a line at the top) would be used to measure variability. The standard deviation represents the average distance of data from the mean. Another measure is variance, which is the standard deviation squared. Lastly, you might use the interquartile range, which is often the range of the middle 50% of the data.
Why are the measures of dispersion necessary to describe a set of data?
Sets of data have many characteristics. The central location (mean, median) is one measure. But you can have different data sets with the same mean. So a measure of dispersion is used to determine whether there is a little or a lot of variability within the set. Sometimes it is necessary to look at higher order measures like the skewness, kurtosis.
