The median can be found out by drawing a perpendicular to the x-axis from the intersection point of both the ogives
The mean is simply the average. Mean = Sum of data divided by the total number of observations.
The ration of a frequency to its total frequency is called relative frequency.
find the frequency before finding the percent total -_- :)
Cumulative frequency is the running total of frequencies. It can be shown on a graph by joining points. For example if frequencies are 4, 6, 3, 2, 6, 10 then their cumulative frequencies are 4, 10, 13, 15, 21 and 31 respectively.
90.5 is the median, as it is the number that is halfway between the two, or half of the total of the two numbers.
By adding up the (one by one,) the frequency total in order to find the cumulative frequency, most commonly, you just then plot this on a cumulative frequency graph or box plot.
The mean is simply the average. Mean = Sum of data divided by the total number of observations.
The ration of a frequency to its total frequency is called relative frequency.
What type of graph is best suited for displaying the range and frequency distribution of the temperature at the airport for two weeks? A. bar graph B. pie chart C. stem-and-leaf plot D. histogram
It is the value halfway between them or half their total. So 27.5 is the median.
find the frequency before finding the percent total -_- :)
Cuban and Puerto Rican populations in the US exceed the median age of the total population, with median ages of 40.2 and 39.5 years, respectively.
Cumulative Frequency is The total of a frequency and all frequencies so far in a frequency distribution. It is the 'running total' of frequencies in the frequency distribution table.
90.5 is the median, as it is the number that is halfway between the two, or half of the total of the two numbers.
Cumulative frequency is the running total of frequencies. It can be shown on a graph by joining points. For example if frequencies are 4, 6, 3, 2, 6, 10 then their cumulative frequencies are 4, 10, 13, 15, 21 and 31 respectively.
a bar graph
The absolute frequency is the total amount of occurances of one variable. The relative frequency is the absolute frequency divided by the total amount of occurances of ALL variables.
