If the mean and median of data is 7 and 8 respectively find its mode?

There is not enough information to be able to determine the mode. The distribution will be left tailed, which will give a clue that the mode is greater than 8. Without the equation of the curve or the actual data, the mode can not be determined.

Does all data have a mean median or mode?
No, not all data sets have a mode but all data sets have a mean and median.
How is a frequency distribution used?
it is used to find mean<median and mode of grouped data
When is the mean not a valid statistic to describe a set of data?
The population data may be skewed and thus the mean is not a valid statistic. If mean > median, the data will be skewed to the right. If median > mean, the data is skewed to the left.
When do you use mean median and mode?
You use mean when you want to find the average of data. You use median to find the middle of a piece of data, ordered from least to greatest. If there is 2 medians, then find the average of those 2 numbers. You use mode when you are trying to figure out the most common piece of data. There can be more than 1 mode.
Which measure summarizes all of the values of a data set with a single number?
The central tendency can be summarised by the mode, median or mean. For qualitative data, only the mode is available.The central tendency can be summarised by the mode, median or mean.

Can ypu find the mean and median with data from a histogram?
You can estimate the median and the mean.
How can you find mean median and mode for GROUPED data?
Mean, median and mode are ways to find averages. The mode is the most common answer in a set of data. The median the number that is in the middle when the numbers are put in order. The mean is the statical average.
Why it is useful to fiNd the meaN mediaN aNd mode of a set of data?
when there are extreme values in the data
Can you find the mean or median of a set of data from a histogram?
You can estimate them both.
Can you find the mean median of a set of data from a histogram?
You can estimate them both.
How do you find the mean and median for dichotomous data types?
To find the mean, you all them all up and divide by how many ever there are. To find the median, you put them in order and the middle one is the median. If there are an even number of data, you take the two in the middle, add them together, then divide by 2.
How do you find the median with an even data set?
The median is the mean of the middle two. For example, find the median of the set {1, 3, 4, 6, 9, 10, 15, 20}. There are 8 items in the data set, so the median is the mean of the middle two. The middle two are the 4th and 5th data items: 6 & 9 median = mean of 6 & 9 = (6 + 9)/2 = 7.5
Does all data have a mean median or mode?
No, not all data sets have a mode but all data sets have a mean and median.
How can determining the mean and median and range help to analyze your experimental data?
Analyzing the mean, median, and range of your experimental data helps establish patters present in the data set. Analyzing the mean will define the quantitative average, analyzing the median will find the number that is center most, and analyzing the range will find the difference between the largest and smallest number in the data set. Good luck!
How is a frequency distribution used?

Should The mean or median be used in ordinal data?
The median is used when reporting ordinal data.
Are the mean median and mode always numbers from a list of data?
the median and mode are but the mean is not
