\nThe mean value can be calculated from both ungrouped and grouped data. Which one do you think is more accurate? Why?
\nAnswer:
\nMean calculated from ungrouped data is more accurate than, mean calculated from the grouped data. Since its calculation takes all the observations in the data into consideration.<\/p>\n
\nWhen it is more convenient to use grouped data for analysis?
\nAnswer:
\nGrouped data is convenient when the values fi<\/sub> and xi<\/sub> are low.<\/p>\n![\"AP](\"https:\/\/apboardsolutions.guru\/wp-content\/uploads\/2020\/12\/AP-Board-Solutions.png\")
<\/p>\n
\nIs the result obtained by all the three methods the same?
\nAnswer:
\nYes. Mean obtained by all the three methods are equal.<\/p>\n
\nIf xi<\/sub> and fi<\/sub> are sufficiently small, then which method is an appropriate choice?
\nAnswer:
\nDirect method.<\/p>\n
\nIf xi<\/sub> and fi<\/sub> are numerically large numbers, then which methods are appropriate to use?
\nAnswer:
\nAssumed – Mean method and Step – Deviation method.<\/p>\n
\nFind the mode of the following data.
\na) 5, 6, 9, 10, 6, 12, 3, 6, 11, 10, 4, 6, 7.
\nAnswer:
\nMode = 6 (most repeated value of the data).<\/p>\n
\nAnswer:
\nMode = 3,7.<\/p>\n
\nAnswer:
\nMode = 2, 3, 4, 5, 6.<\/p>\n
\nIs the mode always at the centre of the data?
\nAnswer:
\nNo. Mode may not beat the centre always.<\/p>\n<\/p>\n
\nDoes the mode change, if another observation is added to the data in Example? Comment.
\nAnswer:
\nIn the example the observations are 0, 1, 2, 2, 2, 3, 3, 4, 5, 6.
\nHere mode = 2.
\nIf we add ‘2’ then mode doesn’t change.
\nIt we add \u20183\u2019 then the mode will be \u20182\u2019 and \u20183\u2019.
\nEven if we add other then 3 the mode will not be changed.
\nSo we cannot decide whether the mode changes or not. It depends on the situation.<\/p>\n
\nIf the maximum value of an observation in the data in Example 4 is changed to 8, would the mode of the data be affected? Comment.
\nAnswer:
\nIf the maximum value is altered to 8, the mode remains the same. Mode doesn\u2019t consider the values but consider their frequencies only.<\/p>\n
\nIt depends upon the demand of the situation whether we are interested in finding the average marks obtained by the students or the marks obtained by most of the students.
\na) What do we find in the first situation?
\nAnswer:
\nWe find A.M.<\/p>\n
\nAnswer:
\nWe find the mode.<\/p>\n<\/p>\n
\nCan mode be calculated for grouped data with unequal class sizes?
\nAnswer:
\nYes. Mode can be calculated for grouped data with unequal class sizes.<\/p>\n","protected":false},"excerpt":{"rendered":"
