45 - 95 = Direct method 45 - 55 = Assumed mean method 55 - 65 = Step deviation method 65 - 75 = Short-cut method
Match the following statistical measures with their corresponding calculation method:
Mean = Sum of all values divided by the number of values Median = Middle value of a data set when arranged in ascending order Mode = Most frequently occurring value in a data set Range = Difference between the highest and lowest values in a data set
Match the following statistical terms with their respective definitions:
Frequency distribution = Organization of data into classes showing the number of observations in each class Grouped frequency table = Tabular arrangement of data into classes along with the corresponding frequencies Statistical measures = Methods used to summarize and analyze data Data set = Collection of values or observations
Match the following statistical concepts with their applications:
Mean = Average score of a group of students in an exam Median = Middle value of temperatures recorded over a period of time Mode = Most common height range among students in a class Range = Difference in wickets taken by bowlers in a cricket match
Match the following data collection tasks with their appropriate data analysis techniques:
Collecting exam marks = Calculating the mean and median scores Recording daily temperatures = Finding the median and range of temperature values Measuring student heights = Determining the mode and range of height distribution Gathering bowling statistics = Analyzing the mean and median number of wickets taken
Match the following mathematical operations with their corresponding statistical interpretations:
Summation = Total value obtained by adding all data points together Subtraction = Difference between two numerical values or observations Multiplication = Repeating addition or combining equal groups Division = Splitting a quantity into equal parts or calculating averages
