What are the middle values in a data set?
the median
What is the middle number in a set data after the data is arranged from least to greatest?
The median value of a range of values.
Is median always part of the data set?
yes* * * * *No. If you have a small, even number of observations, the median is the average of the two middle values. This will usually NOT be part of the data set.
Compute and print the sum of a set of data values?
Compute & print the sum of a set of data values
What are values that divide the data set into four equal parts?
They are called the quartiles. The middle one is also known as the median.
What is the middle value or average of the two middle values in a data set?
The middle value in a data set is the median. If there are an even number of values in the set, you average the middle two values to get the median.
What are the middle values in a data set?
the median
The mean of a set of data is the middle value If there are two middle values it is the mean of the two middle values?
false
The middle value or average of the two middle values in a data set is?
The median.
What is the middle value of a data set when the values are written in numerical order?
Median
What is the middle value when the values are written in numerical order in a data set?
Median
What is the middle number in a set data after the data is arranged from least to greatest?
The median value of a range of values.
Definition of mean median and mode?
Mean is the average of the data set values. Median is the middle number in the data set (set up in ascending or descending order). Mode is the data value (or values) that occur the most number of times.
Why is the median more robust for extreme values?
The median is the middle of average of the middle two values from the ordered set of observations. If the extreme values are genuine then they will have no effect on the median. If they are incorrectly measured or recorded data then they may affect the position of the middle of the ordered set of data. However, since there can only be a small number of outliers, their effect on the median will be small.
Is median always part of the data set?
yes* * * * *No. If you have a small, even number of observations, the median is the average of the two middle values. This will usually NOT be part of the data set.
What is the range median?
range is the distance between the lowest and highest values median is the middle number in a set of data when the data is in numerical order (medium in drink size is in the middle)
There are 100 values in the set The median is 90 the mean is 95 Increase the highest value in the data set by 200 Now what are the median and the mean of the data set?
The median is the middle value (or mean of the two middle values if there are an even number of values) and so is unaffected by an increase in the highest data value. It is still 90. The mean was 95, so the total for the data set was 95x100 = 9500. If the highest data value is increased by 200, the data set total is also increased by 200, giving a new data set total of 9500 + 200 = 9700, so the new mean is 9700/100 = 97.
