Can all quartiles and deciles be expressed in percentiles?
yes! Since Q1 = P25 Q2=P50 Q3=P75 Similarly, D1=P10 D2=P20 . . . D9=P90 Where, Q1, Q2, Q3 are lower, median and upper quartiles respectively Dn are the deciles Good Luck~! Sehrish
How do solve the frequency distribution?
The answer will depend on what you mean by "solve". Find the mean, median, mode, variance, standard error, standard deviation, quartiles, deciles, percentiles, cumulative distribution, goodness of fit to some distribution etc. The question needs to be a bit more specific than "solve".
What is formula of deciles?
D=E1+((dN/10)-Cf)(I)/F The formula of deciles is different for grouped and ungrouped data.
What are percentiles?
p10 eguals
How is the process of determining percentiles different if you were given a sample mean rather than individual raw score?
It is impossible to determine the percentiles if you are given only the sample mean since percentiles are a measure of the spread of the data; the mean gives no information on that.
What is the best type of graph to represent percentiles?
pie chart graph
What type of data would be analyzed for a pie chart?
Percentiles or parts of a whole.
Does percentiles of a raw score differ from the meanof the raw score distribution?
Yes.
How can you convert standard scores to percentiles?
You need to use a table of standard scores.
If your son scored 88 in the quiz what was his percentile in the class?
Your question can not be answered. A tally of all scores in the class is necessary. These are then ranked (lowest to highest), and the percentiles identified. For more information, I suggest you look at percentiles under wikipedia.
Why should you rank your data?
Ranking of data allows calculation of ranges and percentiles. Quick estimation of correlation coefficient is possible (Spearman's method). Certain graphical displays of data, such as box and whiskers plots use percentiles.
How many people die each day and how?
more babies are born than people dying in a ratio of 3:1 maybe
