What else can I help you with?
Can frequency distribution contain more than 10 observations?
Yes. Often hundreds and sometimes (eg in a population Census), millions.
What are some benefits of representing data sets using frequency distributions?
Organizing the data into a frequency distribution can make patterns within the data more evident.
Is a unique mode the same thing as a mode?
No. Some distributions and some sets of observations can have more than one modes. In such cases there is no unique mode.
What is the difference of finding average from raw data and from frequency distribution?
Finding the average from the raw data requires a lot more calculations. By using frequency distributions you reduce the number of calculations.
What are the three frequency distributions and when should each be used?
There are many frequency distributions: Uniform, Binomial, Multinomial, Poisson, Gaussian, Chi-square, Student's t, Fisher's F, Beta, Gamma, Lognormal, Logistic to name some off the top of my head. And I am sure I've missed many more. You need to specify which ones you are interested in. Forgot the Exponential.
What shows the values that a variable can take and the number of observations associated with each value?
measure of central tendency...Updating previous answer by prior responder...I believe the more accurate answer is a frequency distribution.
Who invented skewed distribution?
Nobody invented skewed distributions! There are more distributions that are skewed than are symmetrical, and they were discovered as various distribution functions were discovered.
What are some benefit of using graphs of frequency distributions?
Graphs of frequency distributions provide a clear visual representation of data, making it easier to identify patterns, trends, and outliers. They facilitate quick comparisons between different data sets and help in understanding the overall distribution shape, such as normal, skewed, or bimodal. Additionally, these graphs enhance communication of statistical findings, making complex data more accessible to a broader audience. Overall, they serve as effective tools for both analysis and presentation of data.
How does frequency relate to energy in waves?
In waves, frequency and energy are directly proportional: as frequency increases, the energy of the wave also increases. Higher frequency waves have more energy because they contain more oscillations per unit time, resulting in greater overall energy content. This relationship is described by the equation E = hf, where E is the energy of a wave, h is Planck's constant, and f is the frequency of the wave.
Why have scientist change their ideas on the model of the Atom?
There has been more and more observations about the atom that has changed it since then. They revised it to explain the observations.
How does light pollution impact our environment?
Light pollution has two types of impacts: * A bright sky makes it more difficult for astronomers to smake observations * Local lights can impact breeding cycles and litter sex distributions in several species of animal (e.g. minks). This is important as hte female minks are more valuable to the mink farmer.
What is the difference between formal and informal observations?
Formal observations are planned, structured, and systematic observations that follow a specific protocol or method, such as a checklist or rubric. Informal observations are more relaxed, spontaneous, and subjective observations that may not follow a specific structure or method. Formal observations are often used in research or evaluations, while informal observations are more commonly used in everyday situations or interactions.
