3) Both Mode and median
4)Arithmetic mean​

Answer 1

Step-by-step explanation:

Median

mode.

Arithmetic mean

Answer 2

Answer:

The correct option is (d) Arithmetic mean.

Explanation :

• As is well known, there exist classes for group data that have lower and upper bounds.
• As a result, the group data has open end classes that most likely do not have lower or higher bounds for the first or last class.
• Now that we have a solid understanding of group data with open end classes, we can concentrate on determining which of the following numbers cannot be calculated in this situation.
• We now understand that when group data has open ended classes, the median, mean, and quartiles can be determined.
• Now when we're talking about open end classes, these classes might not have lower limit and upper limit because mode requires the modal class to have lower limit and upper limit.
• As far as we are aware, group data has open-ended classes that most likely do not have lower or upper bounds for the first or last class.
• We also know that median mean and quartiles can be determined even for open-ended classes since they do not require the class to have bounds.
• For the arithmetic mean, this statement is accurate. The existence of extreme items has the biggest impact on the arithmetic mean. It is one of the arithmetic mean's main flaws. Extreme values can easily distort it, and the value of the arithmetic mean may not appear at all in the series.
