A researcher has collected the results of a survey where the participants were asked how many hours of T.V. they watch each day.
The researcher tallies the frequencies for each category and computes mean number of hours watched. She then creates a histogram to help illustrate the overall distribution. Which of the five steps of the statistical process did the researcher apply? a. Design the Study
b. Collect Data
c. Describe the Data
d. Make Inferences
Description of data involves the use of descriptive statistics to analyse/summarize a set of data (from samples) generated during a research.
Some of the process involved in the description of data involves the measure of central tendency ( averages, mean, median mode) and also measure of dispersion and graphing. Therefore, the case above described the data collected.
first you know that you have 2 and 5 as similar numbers you both square them so that they become a ratio of area which is 4/25 after you do 4/25=20/x and you do cross multiply then you find 125. hope that helped understand.
