<h2>Answer</h2>

Stratified sampling

<h2>Explanation</h2>

Stratified sampling is a process of dividing members of the population into homogeneous (separate) subgroups before sampling. Then a random sample is drawn from each group. Members in subgroups may not be fix and subgroups are created under specific type.

<h3>Example</h3>

Subgroup:  Sophomore, Junior, Senior classes

This sampling technique increases the precision of sampling by reducing sample size especially when population size is too large.

In cluster sampling, a random subset of population is created and then random sample drawn from it. Members of all subgroups are equal.

In systematic sampling, fixed intervals from the larger population create the subset of population. Members of all subgroups are equal.

The concept of continuity relates to historical developments and processes because historians can link the happenings in the past to recent occurrences.

  • The concept of continuity simply explains the continuation of a cycle and it shows the connection that exists between historical events.

  • Changes take place at different times which are then linked forward and backward in time. Continuity refers to the continuance of themes.

  • The concept of continuity is vital as historians are able to link what has occurred earlier to the recent things that are happening. For example, Islam had an influence on African culture and its development.

In conclusion, continuity is important to historians.

The Assessment Test asked, "Do I feel disappointed when my achievements go unnoticed?" Do I Agree or Disagree?
Romashka [77]
I would disagree.
It is not always important to be noticed, because you don't have to depend on other people's approval. If you are satisfied with your accomplishments, why does it matter if someone else is going to praise you for them or not? You should be happy, regardless of other people's opinions and thoughts.
