What is the relative frequency of the score of 1 and the frequency of 25?
If I understand the question correctly, it iis 1/25 or 4%
What does highest frequency mean?
In the context of: In the sequence 1,5,8,4,7,2,6,4,8,4,4,4,6,4,4, What number has the highest frequency? It refers to the meaning of what number is most often So the answer is 4 in this case
What is the frequency of the value 8 in the data list 8 0 7 7 9 12 3 7 4 6 7 8 9 6 4?
In the dataset {8, 0, 7, 7, 9, 12, 3, 7, 4, 6, 7, 8, 9, 6, 4} the 8 appears twice. → The frequency of the 8 is 2.
What is the average of 6 12 10 4 3?
The mean average is (6+12+10+4+3)÷5 = 7 The median average is middle number of {3, 4, 6, 10, 12} = 6 There is no mode average as every number appears with the same frequency (of 1).
What is the frequency of a wave that has a speed of 8 ms and a wavelength of 2.0 m?
4 Hz
If the frequency is 4 what is the cumulative frequency?
The cumulative frequency is the running total of numbers, such as, frequency cumulative frequency 4 4 5 11 6 17 7 24 8 32
Give an example of cummulative frequency curve?
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.
What is relative frequency?
Relative frequency is the proportion of all given values in an interval, i.e., the frequency of the event/value divided by the total number of data points.In other words...If you picked 12 marbles out of a bag, and 9 of them were green, the frequency of green marbles would be 9... but the relative frequency would be that number (the frequency) divided by the total number of marbles... so the relative frequency would be 9/12 or 3/4.--Relative frequency is the time that you get something successfully over the total number of times attempted... for example.. you flipped a coin 10 times, and you got heads 4 times. the relative frequency would be 4 over 10.
How many types are there of frequency distribution?
Introduction:Frequency distribution is used to compress and summarize the whole data by grouping the data into classes and records the data points that fall in each class. The frequency distribution is considered as the base for descriptive statistics and they are also used to define the ordinal, nominal and the interval data. Frequency distribution is the comfortable way of grouping and organizing the data.Example of Frequency Distribution:Consider the frequency table for the students in a class where the data has been grouped according to the height of the students. Range of height Total number of student's cumulative frequency3.0 - 4.5 feet 15 154.5 - 5.0 feet 20 355.0 - 6.5 feet 25 506.5 - 7.0 feet 30 80In the case of nominal data the use of the contingency table is required. The frequency distributions are used to present the data graphically.Types of Frequency Distributions:There are three types of frequency distributions. Cumulative frequency distribution,Grouped frequency distribution,Cumulative Grouped frequency distribution.Cumulative frequency distribution (type 1):The cumulative frequency can be found from the frequency distribution by adding the cumulative frequency column. The highest cumulative frequency should be equal to the total number of frequenciesTemperature Frequency Cumulative frequency47 3 2246 3 1945 4 1544 3 1243 3 9Grouped frequency distribution (type 2):The grouped frequency distribution can be formed by grouping the values together into the class intervals.

How do you make a cumalative frequency?
Hi im 15 n i am doing my maths coursework which requires me to make a few cumulative frequency curves. Basically all you do is add the frequency as you go along. for example if the frequencies were: 4 5 2 3 then the cumulative frequency would be 4 9 11 14 You would then use this by plotting it along the y axis. There is a little more but that's mainly what u need to know to get started.
How do you calculate the inter quartiles for these number's 65 71 71 76 77 79 81 82 84 86 87 92 92 103 I get that the median is 81.5 but now I am stuck?
The cumulative frequency curve is shaped like an S. The lower quartile is 1/4 the way up on the cumulative frequency axis. The upper quartile is 3/4 the way up on the cumulative frequency axis The inter-quartile range is the upper quartile minus the lower quartile as plotted on the horizontal axis. Further details can be found in a higher level maths text book.
What does highest frequency mean?

What does 4 sharps in the key signature mean?
4 sharps will be F#, C#, G# and D#. They mean the key of E major, or its relative key of C# minor.
How do you construct a more than type cumulative frequency distribution?
Ogive (Cumulative Frequency Curve) There are two ways of constructing an ogive or cumulative frequency curve. (Ogive is pronounced as O-jive). The curve is usually of 'S' shape. We illustrate both methods by examples given below: Draw a 'less than' ogive curve for the following data: To Plot an Ogive: (i) We plot the points with coordinates having abscissae as actual limits and ordinates as the cumulative frequencies, (10, 2), (20, 10), (30, 22), (40, 40), (50, 68), (60, 90), (70, 96) and (80, 100) are the coordinates of the points. (ii) Join the points plotted by a smooth curve. (iii) An Ogive is connected to a point on the X-axis representing the actual lower limit of the first class. Scale: X -axis 1 cm = 10 marks, Y -axis 1cm = 10 c.f. Using the data given below, construct a 'more than' cumulative frequency table and draw the Ogive. To Plot an Ogive (i) We plot the points with coordinates having abscissae as actual lower limits and ordinates as the cumulative frequencies, (70.5, 2), (60.5, 7), (50.5, 13), (40.5, 23), (30.5, 37), (20.5, 49), (10.5, 57), (0.5, 60) are the coordinates of the points. (ii) Join the points by a smooth curve. (iii) An Ogive is connected to a point on the X-axis representing the actual upper limit of the last class [in this case) i.e., point (80.5, 0)]. Scale: X-axis 1 cm = 10 marks Y-axis 2 cm = 10 c.f To reconstruct frequency distribution from cumulative frequency distribution. When we write, 'less than 10 - less than 0', the difference give the frequency 4 for the class interval (0 - 10) and so on. When we write 'more than 0 - more than 10', the difference gives the frequency 4 for the class interval (0 - 10) and so on.

How do you calculate time given frequency?
periodic time is the reciprocal of frequency , so if the frequency is 4 then the periodic time is 1/4
What is the frequency if the period was 4 seconds?
Frequency = (1)/(period) .If the period is still 4 seconds, then the frequency = (1)/(4 seconds) = 0.25 per second = 0.25 Hz.
