How do you calculate absolute frequencies?
Absolute frequencies are calculated by first identifying intervals based on your data and then identifying the number of values within your data set that lie within these interval. Relative frequencies divide the absolute frequencues by the number of values in the set. It is a good practice to provide the absolute frequencies, perhaps in a bar chart of relative frequencies as a number above each bar.
When should relative frequencies be used when comparing two data sets?
When comparing large data sets.
What is a special type of bar graph that displays the frequencies of data in given intervals of equal width?
Histogram
Frequency and cumulative frequency are two types of what?
Frequency and cumulative frequency are two types of frequency distributions. These are frequency tables that show statistical data for different types of frequencies that include absolute, relative, and cumulative frequencies. There are mathematical formulas used to calculate these frequencies.
What is the difference between measured and reported data?
Reported data is when, on a histogram, the bars are in disproportionate measures. So the bar graph will look all crooked and not uniform. Measured data is the opposite, when the bars on a histogram are uniform and about the same length. Height occurs in uniform order.
Why low frequencies are not used for data transmission in computer networks?
Low frequencies are avoided for data transmission in computer networks to prevent data loss due to attenuation of the signal. Also, low frequencies are incapable of transferring data at the speeds of higher frequencies.
Do 50 percent of married couples in the us end up in divorce?
Short answer - NO. It has been a long-perpetuated statistic but it is NOT accurate because it's not based on reported data but on survey and projection data.
What is transmission bandwidth?
The frequencies which are used to transmit data.
What is the connection between LBD and Alzheimer's disease?
Approximately 40% of patients with Alzheimer's disease also have LBD. Data from autopsy results in Europe and Japan reveal similar frequencies as reported in studies from the United States
What type of data does Bluetooth use?
Digital data sent over UHF radio frequencies.
Graph that is used to compare the frequencies of data?
A dot plot
When the reported data is different from the actual data there is a?
response error.
When the reported data is different from actual data there is a?

Relative frequencies divide the absolute frequencues by the number of values in the set. It is a good practice to provide the absolute frequencies, perhaps in a bar chart of relative frequencies as a number above each bar.
Which choice gives the best representations of frequencies of categorical data from large data sets?
bar graph
When should relative frequencies be used when comparing two data sets?
When comparing large data sets.
Quantitative research is often reported as?
Quantitative research is also known as data, so it is reported as numbers. (Qualitative data is writing.)
